Hi Guys,
I think provided answer is partially correct. What is your opinion ?
Yes, Thanks @Red_devil.
It depends on what you take x and y.
But + 6 and -6 both are possible.
@Chhotu it depends on what you take x and y
if x=-4,y=2 then -2;
if x=4,y=-2 then 2
x= -8/2 & -y = -8/-4 ....x=-4 and y= -2 ....x+y=-6
Answer could be +6 and -6. It depends on choice of X and Y.
Thanks @Red_devil.
@ Chhotu yes 6 and -6 both are possible, they have computed wrong x and y they are -4 ,2 or 2,-4
