Pairs of operations that undo each other

• inverse operations
• solution
• inequality

x + 8 = 15

• x = 23
• x = 7
• x = 120
• x = 15/8

Solve the following equation

8 = m - 12

• 4

• 0.5

• 5.0

• 20

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

Which choice describes the step needed to isolate the variable? (Tap outside of the gray box to see the equation.)

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.
