inequality question
x and y are both > 1. Is x a multiple of y?
(1) 3y^2 + 7y = x
(2) x^2-x is a multiple of y
I can see why 2 does not work, but why does one work?
Thanks in advance

number prop / vic from gmat2 - corrected!
If x and y are greater than 0, is x=1?
1) x/y = 1
2) xy=1
Statement 1 tells us x = 1y -> n.s.
Statement 2 tells us x = 1/y -> n.s.
So now taking 1 + 2, we get: y^2=1 -> y=1 or y=-1
Therefore x is neg or pos 1 ... hence ans is E...
Where am I wrong? cause OA is C...
