Solving Linear Equations Concepts

This video tutorial by Mr. J covers solving one-step and two-step equations. It begins with an introduction to the concept of isolating variables using inverse operations. The tutorial then provides detailed examples of solving one-step equations using addition, subtraction, multiplication, and division. Finally, it explains how to solve two-step equations by reversing the order of operations. Each example includes a step-by-step process and a verification step to ensure the solution is correct.

What is the primary goal when solving equations?

• To multiply all terms by two

• To eliminate all numbers

• To isolate the variable

• To make both sides of the equation equal zero
