Equations with Variables on Both Sides

-7x - 36 = 20 -3x

• -12

• -14

• 15

• 8

14p - 8 = 22 + 20p

• -5

• 5

• 30

12k + 15 = 35 +2k

• k = 2

• k = 4

• k = -2

• k = -4

6x + 5 = 10 + 5x

• x = -5

• x = 6

• x = 4

• x = 5

Solve for x:
5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3

Solve:
2(4x-3) - 8 = 4 + 2x

• x = 5/3

• x = 3

• x = 1

• x = 2

Solve the equation:
-8x - 8 + 3(x-2) = -3x + 2

• x = -8

• x = 8

• x = 2

• x = -2

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation
