Introduction to Solving One-Step Equations

This video tutorial by Mr. J introduces solving one-step equations using inverse operations, focusing on addition and subtraction. The process involves isolating the variable by performing the opposite operation on both sides of the equation to maintain balance. The video provides four examples, demonstrating how to solve equations with variables on either side, and emphasizes checking solutions by substituting the variable back into the original equation.

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

• To eliminate all numbers

• To simplify the equation

• To balance both sides of the equation

• To find the value of the variable
