One thing is you need to get x on one side and y on the other :)
8x-1/3y=16
Just like any equation you subtract 8x
8x-1/3y=16
<u>-8x -8x
</u>-1/3y=16-8x
Now you want y all alone. So you divide. To me I think you divide by -3. But you might want to check and divided by
by -1/3 (just in case)
<u>-1/3y=16-8x
</u> -3
y=-5.33(3 is repeating) - 2.6666667x
I really do this help you out! :D
