Solving One-Step Equations: Addition and Subtraction

The video tutorial explains how to solve one-step equations using inverse operations. It emphasizes the importance of writing down each step rather than solving in your head. The tutorial covers solving equations involving addition and subtraction, demonstrating how to isolate the variable by performing the opposite operation on both sides of the equation. The process is verified by substituting the solution back into the original equation.

Why is it important to write out the steps when solving one-step equations?

• To use more paper

• To make the process faster

• To avoid mistakes and understand the process

• To impress the teacher
