Solving One-Step Equations and Decimals

This video tutorial from MooMooMath teaches how to solve one-step equations with decimals. It covers three types of equations: division, multiplication, and addition. Each type is demonstrated with a step-by-step example, showing how to isolate the variable and solve the equation. The video emphasizes the importance of aligning decimals and performing operations on both sides of the equation to maintain balance.

What is the first step in solving a one-step equation with division?

• Subtract the same number from both sides

• Multiply both sides by the same number

• Add the same number to both sides

• Divide both sides by the same number
