Solving 2-Step Equations with Animation

This video tutorial explains how to solve a two-step equation, 3x + 2 = 8. It demonstrates the process of isolating the variable by first subtracting 2 from both sides to maintain balance, resulting in 3x = 6. Then, it shows dividing both sides by 3 to find that x equals 2. Finally, it emphasizes the importance of checking the solution by substituting the value back into the original equation to ensure accuracy.

What is the initial equation presented in the video?

• 3x - 2 = P

• x + 2 = 3P

• 3x + 2 = P

• 2x + 3 = P
