Solving Two-Step Equations

This lesson teaches students how to solve a two-step linear equation by identifying the operations applied to the variable and undoing them in reverse order. Students practice isolating the variable through addition and division, then verify their solution by substitution.

In this lesson, you will learn to:
• Identify the two operations applied to a variable in a linear equation
• Apply inverse operations in reverse order to isolate the variable
• Solve a two-step linear equation algebraically
• Verify a solution by substituting it back into the original equation
