Answer :

1)Your current problem is in standard form. All you need to do is subtract your X value from both sides leaving you with

-8y= -24x+56

Then divide the entire thing by 8 in order to figure out what y equals

-8y= -24x+56

------------------

-8      -8    -8

If finding the value of Y, your answer should look like this:

y=3x-7

If finding the value of X, you would add your Y value to 56 on the right:

24x=8y+56

Then divide the whole thing by 24 and you get something funky like:

x=(1/3)y+(8/3)

* If in parenthesis, it's meant to be in fraction form.
