x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

x - 32 = 49

• x = 17
• x = 71
• x = 81
• x = 49

• 48

• 3

• 8

• 2

• 5

• 50

The variable, k, is being divided by 11. How should you show your work to solve for the variable?

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