Is x + y > 0 ?

(1) x^2 - y^2 > 1
Both X and y >0 will satisfy.. say 8^2-2^2 and 8+2=10>0......Yes
But both negative can also satisfy...say (-8)^2-(-2)^2 and -8-2<0.....so NO
Insufficient

(2) (x/y) + 1 > 0
Again X/y will be positive for both X and y as positive and also for both as negative..
8/2+1=4+1>0.....yes and 8+2=10>0
(-8)/(-2)+1=4+1>0 but -8-2<0
Insufficient

Combined
Same values 8&2 and -8&-2 will satisfy both statements
Insufficient
