Understanding One-Step Inequalities

This video tutorial by Mr. J covers how to solve one-step addition and subtraction inequalities. It begins with an introduction to inequalities and the concept of isolating the variable using inverse operations. The tutorial then provides step-by-step examples for solving addition inequalities, followed by subtraction inequalities. Each example includes a demonstration of checking solutions to ensure correctness. The video concludes with a summary of the methods discussed.

What is the first step in solving one-step inequalities?

• Add 10 to both sides

• Isolate the variable using inverse operations

• Divide both sides by 3

• Multiply both sides by 2
