Combine Like Terms and Solve Equations

Solve the equation below:

3 (2x + 3) = 21

Solve the equation below. Distribute FIRST and then combine like terms:

3 (4 – 2x) + 4x = 2

• x = 5

• x = 1

• x = –1

• x = –5

Solve for x. Distribute then Combine Like Terms:

–4 (3x – 7) = 4

3c + 5 = 23

-4x+1=21

Solve: 7r - 6.5r = - 20.5

Solve 0.8x + 0.6x = 42

Distribute then combine like terms

-4a - 3(10a - 1)

• -34a + 3

• 15a - 15

• 2a + 7

• 19a - 15
