If x does not equal -y, is (x-y)/(x+y) > 1
1) x>0
2) y<0
[spoiler] My approach was to simplify the given expression as follows:
(x-y)/(x+y) > 1
(x-y) > (x+y)
0>2y
0>y
Statement 1 provides no info about y, hence insuff
Statement 2 confirms y<0, hence sufficient
I chose B, however OA is E
Is it best to plug in numbers for such questions or to simplify as I did?
which is faster?
