### About This Chapter

## Writing & Solving Multi-Step Equations - Chapter Summary

Study the lessons in this chapter to practice writing and solving equations that require multiple steps. Inside the chapter, you'll find short lessons that outline the steps that are needed to solve equations that contain more than one variable. By the end of the chapter, you'll be able to solve the following types of equations/word problems that have two or more variables:

- Addition
- Subtraction
- Multiplication
- Division

To get practice solving multi-step equations, take the accompanying self-assessment quiz that follows each lesson. Your course Dashboard keeps track of your quiz scores, as well as your progress throughout the chapter. You can submit questions to our instructors if you get stuck and study these lessons on any computer or mobile device.
