Solving One-Step Addition and Subtraction Equations

In this video, Mr. J explains how to solve one step addition and subtraction equations. The process involves isolating the variable by using inverse operations to undo the addition or subtraction. The video provides examples for both types of equations, demonstrating how to maintain balance by performing the same operation on both sides of the equation. Each solution is verified by substituting the value back into the original equation. The video concludes with a summary of the methods used to solve these equations.

What is the first step in solving a one-step equation?

• Add a number to both sides

• Divide both sides by a number

• Multiply both sides by a number

• Isolate the variable
