nice question.

x + 2y = 2

(x + y)^2 = 9

x + y = 3 or -3.

...........

x + 2y = 2
x + y = -3
..................................deduct second from the first.
y = 5.

**** anyone can form equation considering x + y =3. but we are looking for possible value . need to consider both aspects.

Out of the 3 ways which i thought of solving this question, inline is the easiest

(x + y)^2 = 9, can be written as x+ y = 3 or x+y =-3

(a)
x+2y = 2
x+y = 3

(b)
x+2y = 2
x+y =-3

b when solved gives us answer as E.

Many of life's failures happen with people who do not realize how close they were to success when they gave up.
