r + 20 = 27

• r = 7
• r = 47
• r = 13
• r = 20

s - 22 = 50

• s = 28
• s = 20
• s = 72
• s = 75

g - 15 = 30

• g = 35

• g = 45

• g = 15

• g = 12

S + 18 = 24

• S = 42
• S = 3²
• S = 18
• S = 4 + 2 

y - 33 = 147

• y = 114
• y = 177
• y = 180
• Answer not Given

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

4b = 24

• b = 12

• b = 6

• b = 28

• b = 4

15 = 3y

• y = 3

• y = 5

• y = 15

• y = 45

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

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

Solve the equation:

4p = 16

• p = 12

• p = -12

• p = -4

• p = 4
