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

What is the first step to isolate the variable in the equation 3x + 2 = P?

• Multiply both sides by 3

• Divide both sides by 3

• Subtract 2 from both sides

• Add 2 to both sides

After subtracting 2 from both sides of the equation 3x + 2 = P, what is the resulting equation?

• 3x = P + 2

• 3x = 6

• 3x = P - 2

• 3x = P

What operation is performed to solve for x in the equation 3x = 6?

• Add 3 to both sides

• Subtract 3 from both sides

• Multiply both sides by 3

• Divide both sides by 3

How do you verify the solution x = 2 in the original equation 3x + 2 = 8?

• Replace x with 2 and check if both sides are equal

• Replace x with 3 and check if both sides are equal

• Replace x with 0 and check if both sides are equal

• Replace x with 1 and check if both sides are equal
