Answer:
x = -2 and y = 0
Explanation:
You just put the value of one variable in terms of the other in one of the two equations. Then, solve it and BOOM you'll have your solution.
x + y = -2 ........... (a)
y = x + 2 ............ (b)
Put (b) in (a),
x + (x + 2) = -2
2x = -4 => x = -2
Put x = -2 in (b),
y = x + 2 = -2+2 = 0
Thus, x=-2 and y=0
