# How do you solve 12=-3(2-2r)-(2r+2) using the distributive property?

x=5

#### Explanation:

Distribute the first term: $- 6 + 6 r$

Distribute second term (-1): $- 2 r - 2$

The question should now look like this: $12 = - 6 + 6 r - 2 r - 2$

Combine like terms: $12 = - 8 + 4 r$

Move 4r and 12 to the other side: $- 4 r = - 8 - 12$

Calculate: $- 4 r = - 20$

Divide both sides by -4: $x = 5$
