Official Solution:
Is \(x > y\) ?
(1) \(\frac{x + y}{x - y} = 1\)
Cross-multiply to ger \(x+y = x-y\). This simplifies to \(2y = 0\), leading to \(y = 0\). The value of \(x\) remains unknown. Not sufficient.
(2) \(x > 0\)
Clearly insufficient.
(1)+(2) Given that \(y=0\) and \(x > 0\), it follows that \(x > y\). Sufficient.
Answer: C

I don't get it? What if I come up with y=0, and I put it in the equation given, I will find that x = 1; thus x>y. That means, I can solve the question without using x>0. Can someone answer me?
