Please include your question in the body of your post .. not just in the title :/

x-y=5      (1a)          becomes       x=5+y  (1b)

-4x+4y=20  (2a)     becomes         -x+y=5     becomes      x=y-5 (2b)

Put these together and we get

5+y=y-5

That is never going to happen :(

So there are no solutions.   Yes it is very sad :((
