The substitution method is a technique for solving a system of equations. This article reviews the technique with multiple examples and some practice problems for you to try on your own.

Solve systems of equations where one of the equations is solved for one of the variables.

Learn to solve the system of equations -3x - 4y = -2 and y = 2x - 5 using substitution. Created by Sal Khan.

It doesn't necessarily matter whether this will be useful in real life, the main point of doing any type of complicated math is to train your brain to use different ways of thinking to come to solutions.

To solve a system of equations using substitution... 1. Isolate one of the variables in one of the equations, e.g. rewrite 2x+y=3 as y=3-2x. 2. You can now express the isolated variable using …

Solve systems of equations where one of the equations is solved for one of the variables.

When solving a system of equations using substitution, you can isolate one variable and substitute it with an expression from another equation. This will allow you to solve for one …

And in this video, I'm going to show you one algebraic technique for solving systems of equations, where you don't have to graph the two lines and try to figure out exactly where they intersect.

Sal demonstrates how to solve a system of three linear equations in three variables using substitution.
