Assuming that you mean
![\dfrac{x+y}{y}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%2By%7D%7By%7D)
if we let
, the expression becomes
![\dfrac{x+4}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%2B4%7D%7B4%7D)
This is an integer if and only if x+4 is a multiple of 4, which in turn happens if and only if x is itself a multiple of 4.
So, the only good options are the multiple of 4, in your case -16.
I don't think there is any difference, because 8-15=-7, and 8+(-15)=-7, because if you remove the parentheses, you will also get 8-15.
Please mark brainiest! Will really really appreciate it!
