Answer:
x=-6, y=3
Explanation:
I will use elimination to eliminate the x variable.
Add the two equations.
-3x-3y=9
3x+8y=6
-------------------
5y = 15
Divide each side by 5
5y/5 = 15/5
y=3
Now we need to find x
3x+8y=6
Substitute y=3
3x+8*3 =6
3x+24=6
Subtract 24 from each side
3x+24-24 = 6-24
3x = -18
Divide each side by 3
3x/3 = -18/3
x=-6
