What is the system of equations?
A system of equations is a set of equations with more than one variable dealing with the same material. If there are 2 variables, then the system must have 2 equations before it can be solved. 3 variables need 3 equations, etc.
How do you solve the equation for x in one step?
It really depends on the equation; except for the most trivial equations, you will usually need more than one step.
What is a sentence with one or more variables?
well, an equation with one variable is a one step equation and an equation with more than 2 variables is a multi-step equation
Can an expression have more than one variable?
Yes, an expression can have more than one variable.
Can a system of equations have more than two inequalities?
A system of equations can have any number of inequalities.
What is to solve equations with more than one operation?
multi-step equations
What are linear equtions and simultanions equations?
Linear Equations are equations with variable with power 1 for eg: 5x + 7 = 0 Simultaneous Equations are two equations with more than one variable so that solving them simultaneously
What is the definition of multi-step equations?
They are equations in which you have to use more than more function to solve the problem.
What is is an equation with more than one variable called?
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.

How do you solve systems by elimination?
Select one equation from a system of linear equations. Select a second equation. Cross-multiply the equations by the coefficient of one of the variables and subtract one equation from the other. The resulting equation will have one fewer variable. Select another "second" equation and repeat the process for the same variable until you have gone through all the remaining equations. At the end of the process you will have one fewer equation in one fewer variable. That variable will have been eliminated from the system of equations. Repeat the whole process again with another variable, and then another until you are left with one equation in one variable. That, then, is the value of that variable. Substitute this value in one of the equations from the previous stage to find the value of a last variable to be eliminated. Work backwards to the first variable. Done! Unless: when you are down to one equation it is in more than one variable. In this case your system of equations does not have a unique solution. If there are n variables in your last equation then n-1 are free to take any value. These do not have to be from those in the last equation. or when you are down to one variable you have more than one equation. If the equations are equivalent (eg 2x = 5 and -4x = -10), you are OK. Otherwise your system of equations has no solution.
Do Equations Having More Than One Variable?
Equations can have as many variables as you want, however to solve an equation you need as many equations as there are unknowns. E.g. in an equation with x & y as the unknowns you would need two different equations containing x and/or y to solve them
Can you have more than one variable?
Yes, you can have more than one variable
Can an expression have more than one variable?
Yes, an expression can have more than one variable.
First Degree Equations and Inequalities in one Variable?
First degree equations ad inequalities in one variable are known as linear equations or linear inequalities. The one variable part means they have only one dimension. For example x=3 is the point 3 on the number line. If we write x>3 then it is all points on the number line greater than but not equal to 3.
