Answer:
x + y = 1
Step-by-step explanation:
If the two equations are the same, then it can be shown by this:
6x + 8 = -4x - 2
We need to isolate the x values, so we need to move the -4x over to the other side making it a +4x:
6x + 4x + 8 = -2
Next, move the +8 over to the other side making it a -8:
6x + 4x = -2 - 8
10x = -10
x = -1
So now we can plug this value into the first equation:
6(-1) + 8 = y
-6 + 8 = y
y = 2
x + y = -1 + 2 = 1
So x + y = 1
