Solving One-Step and Two-Step Equations

The video tutorial explains how to solve two-step equations, emphasizing the importance of removing constants and isolating variables. It provides examples, such as solving 2x + 5 = 13 and 3B + 8 = 14, and discusses strategies for rearranging equations. The tutorial also covers handling negative numbers, solving equations with division, and dealing with parentheses. The consistent approach is to isolate the variable by removing constants and using inverse operations.

What is the first step in solving the equation 2x + 5 = 13?

• Subtract 5 from both sides
