Exploring One Step Equations

The video tutorial explains how to solve one-step equations by using inverse operations. It begins with an introduction to equations, describing them as math sentences that show equality between two expressions. The tutorial then explains inverse operations, which are operations that undo each other, such as addition and subtraction or multiplication and division. The main focus is on solving one-step equations by identifying the operation used and applying the inverse operation to isolate the variable. The tutorial includes examples to demonstrate the process, ensuring learners understand how to apply these concepts to solve equations.

What is an equation?

• A math sentence that shows two expressions are different.
