Introduction to Solving One-Step Equations

In this video, Mr. J introduces solving one-step equations by isolating the variable using inverse operations. The tutorial covers solving equations involving addition, subtraction, multiplication, and division. Each example demonstrates the process of using the opposite operation to maintain balance and equivalence in the equation. The video emphasizes the importance of performing the same operation on both sides of the equation to isolate the variable and verify the solution.

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 largest number possible
