Equations and Inequalities

Overview

This chapter builds on the basics of algebra (Chapter 3) to prepare students for future algebra courses. After an introduction to writing equations, students turn to solving equations, first one-step and then two-step linear equations. The first half of the chapter closes with a presentation on solving equations with grouping symbols. The chapter ends by discussing the solving and graphing of one-step and two-step inequalities.

What you can expect to learn

After completing Chapter 6 you should be able to

  1. Write algebraic equations and inequalities that model mathematical and real-world problems.
  2. Solve one- and two-step algebraic equations and inequalities.
  3. Solve equations involving groupings.
  4. Defend the claim that models rely on an orderly universe.
