One-Step Equations and Operations

Mr. Hammondre explains how to solve one-step equations using multiplication, addition, division, and subtraction. Students are instructed to follow along by writing down examples and steps, which they will present to their math teacher. The lesson covers the importance of isolating the variable and checking solutions. Each type of problem is demonstrated with examples, and students are encouraged to practice and verify their answers.
