Answer:
Step-by-step explanation:
find the value of y in the second equation
x + y = -2,
but y = -2-x as well
so take the value that we have found for (x) into the first equation
2x + 2(-2-x)= 8
-2x + -4-2x = 8
-4x-4=8
-4x = 12
x=-3,
now just substitute x value into either equation
x + y =-2
-3 + y = -2
y =1
