In this lesson, we learn how to solve systems of equations using the substitution method. The goal is to get either x or y by itself and then replace that variable with the expression in the other equation. We solve for one variable, y in this case, and then plug that into the other equation to find the value of the other variable, x. The final answer is given as an ordered pair.
