Mastering One Step Equations with Multiplication and Division

Mr. Cassidy continues the exploration of one-step equations, reviewing addition and subtraction before introducing multiplication and division. The lesson covers how to identify operations affecting variables and how to solve equations by applying inverse operations. Students are guided through practice problems to reinforce their understanding of balancing equations and using multiplication and division to isolate variables.
