Solving One-Step Equations

This video tutorial covers solving one-step equations, a fundamental concept in algebra. It explains how to solve equations by performing the inverse operation: subtracting to undo addition, adding to undo subtraction, dividing to undo multiplication, and multiplying to undo division. The tutorial includes four examples demonstrating these principles, emphasizing the importance of performing the same operation on both sides of the equation to maintain balance.
