Solving Multi-Step Equations with Variables on Both Sides

This video tutorial by Mr. J introduces solving equations with variables on both sides. It explains the process of isolating the variable on one side of the equation using inverse operations. Two examples are provided: one solving for x and another for y, demonstrating the step-by-step approach to reach the solution. The video concludes with a summary of the key steps involved in solving such equations.

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

• Multiply both sides by the variable

• Isolate the variable on one side

• Subtract the variable from one side

• Divide both sides by the variable

Why is it suggested to avoid negatives when isolating variables?

• To simplify calculations

• To ensure the variable is on the left side

• To make the equation more complex

• To avoid division by zero
