It should be "E" i.e -2

Edit: Not sure, with y = -2, I'm getting x = -2 but x is not equal to y :(

Other choices,
for y = -1, x = infinity :shock:
for y = 0, x = 0 (again x = y)
for y = 1, x = -0.5 but both have to be integers
for y = 2, x = -2/3

I'll go mad.

hik, sorry buddy, i just editted. It's " x is not equal to 0" :oops:

buddy, you know children are extremely sensitive to learning around the age of Tanvi ....they will learn a lot from their parents' emotional expressions. Just keep showing her all your happiness and smiling so that she'll be an optimistic person later!! ^_^

x+y+xy = 0 --> x(y+1) +y = 0 ---> x(y+1) + (y+1) -1 =0
---> (y+1) (x+1) =1

Because x and y are integers ---> (y+1) and (x+1) must be factors of 1
We have two cases:
(y+1) = 1 and (x+1) =1
OR ( y+1) =-1 and (x+1) = -1
But the first case yields x= 0 ---> eliminate
The second case stands ---> y+1= -1 ---> y=-2

OA is E.
Good job, everyone~!! :)

x+ y + xy = 0

===> 1/x + 1/y = -1
put value of Y from the given choices and try to find out X.

from the give choices

Only E satisfy the condition that both x and y should be an Integer.
