Solving Addition Equations Using Inverse Operations (Example)

The video tutorial explains how to solve the equation X + 95 = 120 using inverse operations. It begins by introducing the equation and the concept of inverse operations. The tutorial then demonstrates how to solve the equation by subtracting 95 from both sides to isolate X, resulting in X = 25. Finally, it verifies the solution by substituting 25 back into the original equation, confirming that 25 + 95 equals 120.

What is the initial equation we are trying to solve?

• X + 120 = 95

• X - 120 = 95

• X - 95 = 120

• X + 95 = 120

What operation should be performed to isolate X in the equation X + 95 = 120?

• Multiply both sides by 95

• Add 95 to both sides

• Subtract 95 from both sides

• Divide both sides by 95

After subtracting 95 from both sides of the equation, what is the resulting equation?

• X = 0

• X = 95

• X = 25

• X = 120

What value of X makes the equation X + 95 = 120 true?

• 95

• 0

• 25

• 120

How do we verify that our solution for X is correct?

• By adding 95 to X

• By substituting X back into the original equation

• By multiplying X by 95

• By dividing X by 95
