Two Step Equations and Combining Like Terms

Combine like terms and then solve the 2-step equation:

6x + 4 + 2x = 20

• x = 8

• x = 2

• x = 3

• x = 4

Combine like terms and solve the 2-step equation:

3 + 12c - 4c = 35

• c = 4

• c = 2

• c = 4.75

• c = 3.18

Combine like terms and solve the 2-step equation: 10 + 6x - 4 = 30

• x = 2.6

• x = 6

• x = 4

• x = 7.3

Combine like terms and solve the 2-step equation:

3x + 20 - 5 = 36

• x = 17

• x = 3.6

• x = 20.3

• x = 7

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

Solve: 5x - 4 + 2x = 3

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

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• add 1 to both sides

Solve: 2x - 3 + 4x = 27
