Solving Equations and Inequalities

Mr. Holcomb presents a lesson on true and false number sentences, starting with a classwork exercise. He explains how to determine if a number sentence is true or false and provides examples using substitution and solving equations. The lesson includes exercises for students to practice solving equations and inequalities using inverse operations.
