Solving a two step equation

The video tutorial explains how to solve a two-step equation involving a variable X. The instructor begins by introducing the equation and the goal of finding the value of X that makes the equation true. The process involves understanding the equation, undoing addition and subtraction, and then using multiplication to isolate the variable. The solution is verified by substituting the value back into the equation to ensure correctness.

What is the main goal when solving a two-step equation?

• To make both sides of the equation zero

• To add more variables to the equation

• To change the equation into a one-step equation

• To find the value of the variable that makes the equation true

What is the first step in solving the equation X/2 + 4 = 3?

• Multiply both sides by 2

• Subtract 4 from both sides

• Add 4 to both sides

• Divide both sides by 2

After subtracting 4 from both sides, what is the resulting equation?

• X/2 = -1

• X/8 = -1

• X/2 = 7

• X/8 = 1

What operation is used to isolate X after simplifying to X/8 = -1?

• Add 8 to both sides

• Divide both sides by 8

• Multiply both sides by 8

• Subtract 8 from both sides

What is the final value of X in the equation X/2 + 4 = 3?

• -8

• 4

• -4

• 8
