Solving Inequalities with Addition and Subtraction

This video tutorial covers Chapter 6, Lesson 6 on solving one-step equation inequalities using addition and subtraction. It introduces the concept of inequalities, explains the addition and subtraction properties of inequalities, and provides examples to illustrate these properties. The tutorial also demonstrates how to graph inequalities on a number line and includes practice problems for students to solve, followed by a review of the solutions.
