Solving Two-Step Equations

The video tutorial explains how to solve a two-step equation. It begins by introducing the concept of two-step equations and proceeds to demonstrate the first step, which involves moving a constant to the other side of the equation to balance it. The second step involves dividing by the coefficient to isolate the variable. The tutorial concludes with a verification process, substituting the solution back into the original equation to ensure its correctness.

What is the first step in solving a two-step equation?

• Subtract the same number from both sides

• Multiply both sides by the same number

• Divide both sides by the same number

• Add the same number to both sides
