15-12n=n+2? Do you want to find n? 15=13n+2 (add 12n to each side) 13=13n (subtract 2 from each side) n=1 (divide both sides by 13)
n = 3
n = 2
2
-4
n + 17 = 2 n = 2 - 17 n = -15
2 plus n is the true one, but 1 plus n is not?
2 plus 2 plus n equals 6 n equaling 2
5-2=3n=3
n = 28
N = -36
The answer to the question is 9.
