Understanding One-Step Equations with Decimals

The video tutorial explains how to solve one-step equations involving decimals using the division property of equality. It provides two examples, demonstrating the process of dividing both sides of the equation by the coefficient to isolate the variable. The tutorial emphasizes the importance of handling decimals carefully and offers tips for using calculators if allowed.
