5.2 Solving Systems Using Substitution

5.2 Solving Systems Using Substitution

Author: James Bailey

1. At the end of this lesson, you will be able to use the substitution method to find an ordered pair that satisfies two equations when at least one is written with a variable by itself.

2. At the end of the lesson, you will be able to use the substitution method to solve systems of equations written in any form.


In this tutorial, students are asked to watch two videos that show examples of solving systems using substitution. Students can choose to read the text as opposed to watching videos. They will be asked to complete their success packet and answer 4-6 summary questions.
