Solving One-Step and Two-Step Equations

The video tutorial covers solving one-step and two-step equations. It begins with an introduction to equations, explaining what they are and how to identify the variable to solve for. The tutorial then demonstrates solving two-step equations using inverse operations, such as addition and subtraction, to isolate the variable. It emphasizes the importance of checking solutions by substituting them back into the original equation. The video also covers solving one-step equations and verifying the solutions, ensuring students understand the process thoroughly.

What is an equation?

• A math statement with an equal sign

• A math statement with a plus sign

• A math statement with an inequality

• A math statement with a variable

What is the first step in solving for the variable X in a two-step equation?
