Solving One and Two-Step Inequalities Challenge

This video tutorial teaches how to solve one and two-step inequalities by extending the understanding of solving equations. It reviews solving equations using inverse operations and introduces the concept of flipping the inequality sign when multiplying or dividing by a negative number. The tutorial provides step-by-step instructions for solving both one-step and two-step inequalities, including graphing solutions and checking answers. Practice problems are included to reinforce learning.

What is the first step in solving an equation?

• Multiply both sides by the same number
