Equations With Variables on Both Sides

Which answer is the solution to the following equation?

30a-24=5a+26

• a=1

• a=1.3

• a=2

• None of these

-10x - 135 = 117 + 2x

• 25

• -18

• -21

• 22

-49 - x = -8x + 70

• 15

• 17

• 14

• 19

-7x - 36 = 20 -3x

• -12

• -14

• 15

• 8

7x - 4 = 3 + 8x

• x = 7

• x = -7

• x = 2/7

• x = 11

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

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
