-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

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 is the first step you should take to solve this problem?

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

What is the next step you should take?

1 + 4n = 10 - 14n

• Collect the variables (letters) to the left

• add 1 from both sides

• subtract 14n to both sides
