Solving Subtraction Equations Using Inverse Operations (Example)

The video tutorial explains how to solve the equation m - 8 = 3 by isolating the variable M. The process involves adding 8 to both sides of the equation to cancel out the minus 8, leaving M alone on one side. The final solution is m = 11.

What is the initial equation presented in the video?

• m / 8 = 3

• m + 8 = 3

• m - 8 = 3

• m * 8 = 3

What is the first step to isolate the variable M in the equation?

• Multiply both sides by 8

• Subtract 8 from both sides

• Add 8 to both sides

• Divide both sides by 8

Why do we add 8 to both sides of the equation?

• To balance the equation

• To make the equation more complex

• To eliminate the variable M

• To simplify the equation

What happens to the minus 8 and plus 8 in the equation?

• They add up to 16

• They cancel each other out

• They remain unchanged

• They multiply to 64

What is the final value of M after solving the equation?

• M = 11

• M = 3

• M = 8

• M = 0
