## CHAPTER 9: LINEAR RELATIONS AND LINEAR EQUATIONS

**Lesson 3: Exploring Possible Values **

**Goal**

Explore possible values for variables in a given equation.

**Instructions for Use**

**Weigh the Wangdoodles **

Read the introduction and click on “Start.”

Your job is to find the weight of each Wangdoodle using the information provided by the three equations that represent the weigh scales. To be successful, you will have to make sure that the weight you assign to each Wangdoodle works on each scale.

When you are sure your values for each Wangdoodle are correct, click “Check It.” Click on “New Puzzle” to get a new set of Wangdoodle equations.
