158 Chapter 3 Solving Equations Section 3.4 Practice Exercises Study Skills Exercise A good way to determine what will be on a test is to look at both your notes and the exercises assigned by your instructor. List five types of problems that you think will be on the test for this chapter. Vocabulary and Key Concepts 1. Consider equation 3x 6 18. According to the recommended procedure to solve a linear equation, should we add 6 to both sides first, or should we divide both sides by 3 first?
