Solving Two Step Inequalities in 7th Grade Math

This tutorial covers solving and graphing two-step inequalities. It explains how to handle different inequality signs, isolate variables, and find solution sets. The video demonstrates graphing solutions on a number line, using open and closed circles. A bonus example addresses handling negative variables in inequalities.

What is the first step in solving a two-step inequality?

• Graphing the inequality

• Isolating the variable

• Adding the same number to both sides

• Finding the solution set
