You can put this solution on YOUR website! Check the set of equations USING the x and y which you found and see if both equations are satisfied.
---
-8x+4(-8-4x)=-8
-8x-32-4x=-8
-12x-32=-8
12x+32=8
12x=8-32
12x=-24
x=-2
Now you find y.

y=-4x-8
-8x+4y=-8
Please show step by step work, so I can see if the answer I have is correct.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
y = -4x - 8 (1)
-8x + 4y = -8 (2)
You just have y expressed via x in equation (1).
So, simply substitute it into equation (2). You will get a single equation for x:
-8*x + 4*(-4x - 8) = -8.
Simplify and solve it:
-8x - 16x - 32 = -8,
-24x = -8 + 32,
-24x = 24,
x = = -1.
Now from (1) y = -4x - 8 = -4*(-1) - 8 = 4 -8 = -4.
Answer. x = -1, y = -4.

You didn't show your work, or reveal your answers.
For that reason, I won't show mine either but I'll tell you this much:
