To solve a system of equations using the substitution method, first, solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation to eliminate that variable. This will result in a single equation with one variable, which can be solved for its value. Finally, substitute this value back into the original equation to find the value of the other variable.
What else can I help you with?
When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?

What is the advantage that the method od substitution has over the graphing method of solving system of equations?
Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
How do you decide whether to use elimination or subsitution to solve a three-variable system?
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
How do you slove systems of two equations?
To solve a system of two equations, you can use one of three methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you manipulate the equations to eliminate one variable by adding or subtracting them. Graphing involves plotting both equations on a graph and identifying their point of intersection, which represents the solution.
How can you use substitution method to solve a system of equations that does not have a variable with a coefficient of 1 or - 1?
To use the substitution method on a system of equations without a variable with a coefficient of 1 or -1, you first isolate one variable in one of the equations. For instance, if you have the equations (2x + 3y = 6) and (4x - y = 5), you can solve the first equation for (y), resulting in (y = (6 - 2x)/3). Next, substitute this expression for (y) into the second equation, allowing you to solve for (x). Finally, substitute the value of (x) back into one of the original equations to find the corresponding value of (y).

What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system.?
When using the substitution method to solve a nonlinear system of equations, the first step is to isolate one variable in one of the equations, if possible. This allows you to express that variable in terms of the other variable. You can then substitute this expression into the other equation, transforming the system into a single equation with one variable, which can be solved more easily. Once you find the value of one variable, you can substitute it back to find the other variable.

Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
