### About Multi-Step Equations:

We previously learned how to use the addition property of equality to solve equations such as: x + a = c. We also learned how to use the multiplication property of equality to solve equations such as: ax = c. We will now use both of these properties to solve a multi-step equation such as: ax + b = c.

Test Objectives

- Demonstrate an understanding of the addition property of equality
- Demonstrate an understanding of the multiplication property of equality
