I feel ans should be 'E' here.
From 1: z <0
so, from the given equation (x+y)/z=-2
(x+y) should be >0 but we have no idea about y here.In sufficient
From 2: y>0
but no idea about z and x here.So in sufficient .
Combining both we know (x+y) >0 and y >0 , however we still can't find if x is < or > 0 . So insufficient.
