Solving Multistep Equations with Variables on Both Sides

This video tutorial focuses on solving multi-step equations, particularly those with variables on both sides of the equal sign. It provides examples and step-by-step instructions on how to simplify and solve these equations using techniques like combining like terms and applying the inverse operation. The tutorial also covers the use of the distributive property and offers a challenge problem to reinforce learning. Throughout, the importance of checking solutions is emphasized.

What is the first step in solving equations with variables on both sides?

• Combine like terms on the same side

• Move all variables to one side using inverse operations

• Distribute values inside parentheses

• Subtract constants from both sides

What operation is used to move a positive term across the equal sign?

• Division

• Multiplication

• Subtraction

• Addition
