r + 20 = 27

• r = 7
• r = 47
• r = 13
• r = 20

• Add 5 to both sides

• Add 20 to both sides

• Subtract 5 from both sides

• Subtract 20 from both sides

• x = 25

• x = 15

• x = 5

• x = 20

• Subtract 7 from both sides

• Add 7 to both sides

• Subtract 3 from both sides

• Add 3 to both sides

• y = 4

• y = -21

• y = -4

• y = 10

• g = 5

• g = 10

• g = 15

• g = -5
