Identify the property of equality used & the solution.

• division: 7
• addition: - 40
• multiplication: - 30
• division: - 7

20 = 9k + 2

-2 -2

-----------------

18 = 9k

What should you do next?

• multiply both sides by 18

• multiply both sides by 9

• divide both sides by 18

• divide both sides by 9

8x + 28 = 5x + 52

• x = 8

• x = 27

• x = 2

• x = 10

3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12
