I'm guessing you need to solve for x and y.
Rewrite the second equation and then add to the first equation to eliminate y temporarily.
6x + 2y = -8
3x - 2y = -28
------------------
9x = -36
x = -4
Then substitute -4 in for x into the first equation.
6(-4) + 2y = -8
2y = -8 + 24
y = 16/2 = 8
x = -4, y = 8
