If x+2/Y-3 = 0 then, which of the following are true?
A) x = 2 and y = 3
B) x = 2 and y =/= 3
C) x = 0 and y = 0
D) x = -2 and y = 3
E) x = -2 and y =/= 3
The official answer is E; X = -2 and Y =/=3
But I do not understand why it cannot be D as well: X = -2 and Y = 3
(-2) + 2 / (3) -3 = 0 ; why is this not valid?
(I am sorry, I do not have enough of a reputation to paste an image of the question, which would make reading this question so much easier)

You can't have y = 3 as that would imply a division by 0, which is undefined. In more rigorous terms, the LHS exists if (but not only if) y is different from 3, so any root of that equation is a solution only if y =/= 3.
