Is x > y?
(1) x + y < 0
(2) x - y > 0
The right answer is supposed to be B, but I think it should be D. Here's how I came to that conculsion.
(1):
x + y < 0
so x < -y
so x > y <- is this wrong??
SUFFICIENT
(2):
x - y > 0
so x > y
SUFFICIENT
So, where did I go wrong?
Thanks in advance for any help offered.

for (1), you made the negative sign disappear from your 2nd to last step to your last step. It shouldn't just disappear like that. If you switch the direction of the > sign, then the other side becomes negative .. so either x<-y or -x>y .. but negative sign doesn't go awayanthoj wrote:Is x > y?
