Using Substitution Method:
x + y = -2    ----equation 1
2y = 8     -------equation 2
--------------------------------------
From equation 2
2y = 8
Divide the whole equation with 2
(2y = 8) ÷ 2
y = 4
--------------------------------------
Substitute y=4 to equation 1
x + y = -2
x + 4 = -2
x = -2 - 4
x = -6
--------------------------------------
Therefore the values of x and y are -6 and 4 respectively.
