Answer:

x = -2 and y = 0

Step-by-step 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
