How do you solve a linear system using substitution?
Suppose you have n linear equations in n unknown variables. Take any equation and rewrite it to make one of the variables the subject of the equation. That is, express that variable in terms of the other (n-1) variables. For example, x + 2y + 3z + 4w = 7 can be rewritten as x = 7 - 2y - 3z - 4w Then, in the other (n-1) equations, plug in that value for the variable and simplify (collect like terms). You will end up with (n-1) equations in (n-1) unknown variables. Repeat until you have only one equation in 1 variable. That gives you the value of one of the variables. Plug that value into one of the equations from the previous stage. These will be one of two equations in two variables. That will give you a second variable. Continue until you have all the variables. There are simpler methods using matrices but you need to have studied matrices before you can use those methods.

Why are parametric eqautions bad?
In mathematics, parametric equations of a curve express the coordinates of the points of the curve as functions of a variable, called a parameter.[1][2] For example,are parametric equations for the unit circle, where t is the parameter. Together, these equations are called a parametric representation of the curve.A common example occurs in kinematics, where the trajectory of a point is usually represented by a parametric equation with time as the parameter.The notion of parametric equation has been generalized to surfaces, manifolds and algebraic varieties of higher dimension, with the number of parameters being equal to the dimension of the manifold or variety, and the number of equations being equal to the dimension of the space in which the manifold or variety is considered (for curves the dimension is one and one parameter is used, for surfaces dimension two and two parameters, etc.).The parameter typically is designated t because often the parametric equations represent a physical process in time. However, the parameter may represent some other physical quantity such as a geometric variable, or may merely be selected arbitrarily for convenience. Moreover, more than one set of parametric equations may specify the same curve.
How do you solve a system of equation with 3 equations and 3 variables?
If you know matrix algebra, the process is simply to find the inverse for the matrix of coefficients and apply that to the vector of answers. If you don't: You solve these in the same way as you would solve a pair of simultaneous linear equations in two unknowns - either by substitution or elimination. For example, change the subject of one of the equations to express one of the variables in terms of the other two. Substitute this value into the other two equations. When simplified, you will have two linear equations in two variables.

How solve systems of equations?
The answer will depend on the nature of the equations and the level of your knowledge.Probably the simplest way to deal with a general problem is to do it graphically. As long as you can calculate the values of the equations, you can plot them and the solutions are a subset of the points of intersection.If the equations are all linear and do have a solution then inverting the matrix of coefficients is probably simplest way. In some respects this is likeselecting one equation,using it to express on variable in terms of the others,substituting the expression for that variable in all the other equations.That reduces the number of equations and variables by one. Continue until you have just one variable whose value you can determine. Substitute this value in one of the last two equations and you will then have two known variables. Go back up the line until you have them all.
What are the types of operations used to solve linear equations?
There are various processes:Trial and error. It can sometimes work. Not recommended, but it can work sometimes, particularly if there are external factors that suggest values for some of the variables.Plotting the lines represented by the equations to find their point(s) of intersection. Good for two variables, just about feasible with three but not sensible for more variables.Substitution involves using one equation to express one of the variables in terms of the others. The next step is to substitute for that variable in the remaining equations. Repeat the process and, step-by-step, reduce the number of variables and equations to one. Solve that equation and then work back. Elimination is an equivalent method and uses linear combinations of the equations to eliminate one variable at a time from the system of equations so as to arrive at a single equation in one variable. Suppose the system of n equations in n variables is represented in matrix form by Ax = y where A is the nxn matrix of coefficients of the equations, and x is an m*1 column vector of variables and y is a m*1 vector of constants. Then the solution (if it exists) is A-1y, where A-1 is the inverse matrix of A.

How do you slove 11x plus 6y equals 58?
You cannot solve one linear equation in two unknown variables (x and y), although some non-linear equations will suffice. You need two independent linear equations. All you can do is express one of the variables in terms of the other, but that is not solving the equation.
How do you solve a simultaneous equation with 3 variables?
You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.
How do we use variables in the real wold?
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
What is a easy definition of an independent variable?
Independent variables, namely a quantity change will not cause except the dependent variable other than the amount of change. Only by the independent variables to a physical quantities to express, it is by the function relation is correct The dependent variable, a quantity change will cause in addition to other than the dependent variable amount change. Put the dependent variables as independent variable, is to determine the relationship between a big physical quantities. Variables, it is to point to have no fixed value, can change the number Constant DuoZhong type, and every type is there is a data type, have integers, bytes, characters, floating point, enumeration, etc.
How do you solve a linear eqution when there are two letter on the same side?
You cannot solve a single linear equation with two variables. At best you can express one variable in terms of the other.
