Introduction to Solving One-Step Equations

This video tutorial by Mr. J introduces solving one-step equations, focusing on multiplication and division. It explains the concept of isolating variables using inverse operations and demonstrates this through four examples. Each example shows how to solve an equation by performing the opposite operation on both sides to maintain balance. The video concludes with a summary of the methods discussed.

What is the main goal when solving one-step equations?

• To make both sides of the equation equal zero

• To isolate the variable

• To eliminate all numbers from the equation

• To find the value of the constant

What is the inverse operation of division?

• Multiplication

• Subtraction

• Division

• Addition
