Understanding One-Step Equations

The video tutorial explains how to solve the one-step equation X + 8 = 5. It begins with a fast motion demonstration of subtracting 8 from both sides to isolate X, resulting in X = -3. The tutorial then provides a slow-motion, detailed explanation of using opposite operations to solve the equation. Finally, it verifies the solution by substituting -3 back into the original equation to ensure the result is correct.

What is the first step in solving the equation X + 8 = 5?

• Add 8 to both sides

• Subtract 8 from both sides

• Multiply both sides by 8

• Divide both sides by 8
