Distributive Property and Combining Like Terms

Use the distributive property and combine like terms:

4x + 2(x - 1)

• 6x - 2

• 4x + 2x - 2

• 6x - 1

• 8x + 2x - 2

Use the distributive property and combine like terms:

2(x + 8) + 6x

• 2x + 8 + 6x

• 8x + 8

• 8x +16

Simplify by combining like terms: 7v - 2 + 12 + 2v

• 23

• 23v

• 9 + 14v

• 9v + 10

Simplify by combining like terms:

5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4
