Module 5: Solving Linear Equations

As the name implies, a linear equation is an equation whose graph is a line. There are linear equations that include one variable, such as 5y + 8 = 20. There are also linear equations that include more than one variable, for example 5x - 6y = 18. Understanding how to solve these types of equations and how to use them to model real-world problems is the focus of this module.

Module Getting Started

There are many properties that make it possible for you to solve a linear equation. In fact, you may have learned about many of these properties in some of your earlier math courses. Take a look at the properties listed below in the Key Vocabulary box. Create two lists: one that includes the properties you are already familiar with and another that includes any properties that are new to you. As you complete each topic, review your "new" list to see if you are able to move any properties to your other list. Make sure you are able to define every property listed below by the time you complete this module.
