Solving One-Step Equations with Addition and Subtraction

In this video, Kaylee teaches how to solve one-step equations using addition and subtraction. The tutorial covers solving equations like x + 6 = 8, y + 25 = 100, y - 14 = 20, and -5 + t = 4. Each example demonstrates using inverse operations and checking solutions through substitution. The video emphasizes doing the same operation on both sides of the equation to isolate the variable.

What is the purpose of using inverse operations in solving equations?

• To isolate the variable

• To change the equation's solution

• To add more variables

• To make the equation more complex
