Answer: n=13/2 or n=6 1/2

Explanation:

use pemdas to solve take -4 and multiply what’s in the parentheses. Then add 12n+ 20n. Then subtract -28-180. Your left with -32n=-208 after divide both sides by -32 and your left with n=13/2

Answer: n= 4.25

Explanation:

First, distribute the -4.

108= 12n+20n-28

Next, simplify.

108= 32n-28

Isolate n by adding 28 to both sides.

136= 32n

Divide both sides by 32 to get n by itself.

n=4.25
