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
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
