Solving Systems of Equations by Substitution

Hopefully you have already learned how to solve systems of equations by graphing. If not, view our guide here.

Now we’re going to learn how to solve them by using algebra and a method called substitution.

Again, let’s look at the same two equations:

Equation 1: Equation 2:
