Understanding Two-Step Inequalities

In this video, Mr. J explains how to solve two-step inequalities by isolating the variable using inverse operations. He emphasizes the importance of flipping the inequality symbol when multiplying or dividing by a negative number. The video includes a detailed example of solving the inequality 7X - 3 > 18, demonstrating each step and verifying the solution with a test value. Mr. J concludes by providing links to additional examples and resources for further practice.

What is the primary goal when solving a two-step inequality?

• To find the value of the variable

• To isolate the variable on one side

• To eliminate all numbers

• To make both sides equal
