Is there any shorter way of doing this question beside plugging in the values?

Q.) If x is not equal to -y, is (x-y)/(x+y) > 1 ?
1) x>0
2) y<0

Plugging in values is extremely efficient if you try combinations that satisfy both statements.

Let x=2 and y=-1.
Is (2-(-1)) / (2+(-1)) > 1? Yes.
Let x=1 and y=-2.
Is (1-(-2)) / (1+(-2)) > 1? No.

Since the combinations above satisfy both statements, and in the first case the answer is Yes and in the second case the answer is No, the correct answer is E.

Hi Mitch,

Can we do like this

x-y/x+y>1

= x-y>x+y
= -2y>0
= y < 0

this nothing but option B) so B is correct

so answer is B)

is this wrong way of approach????
