Equations With Variables on Both Sides

7x = 4x + 33

• 3

• 11

• 21

• 88

Which statement best describes the first step to the equation? -11-3x=44-2x

• Add 3 to both sides

• Add 11 to both sides

• Get the variables on one side

• Add 2 to 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

5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3

14p - 8 = 22 + 20p

• -5

• 5

• 30

6x + 5 = 10 + 5x

• x = -5

• x = 6

• x = 4

• x = 5

Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

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
