Just solve for y, then replace " y " by " f(x) ".
That's all there is to it:

   4x+-+6y+=+-30
    -6y+=+-30+-+4x
Divide thru every term by -6
   +%28-6y%29%2F%28-6%29+=+%28-30%29%2F%28-6%29+-+%284x%29%2F%28-6%29+      
      +y+=+5+%2B+%284x%29%2F6+
      +y+=+5+%2B+%282x%29%2F3+ 

Now replace y by f(x)

     +f%28x%29+=+5+%2B+%282x%29%2F3+

4X-6Y=-30
4X=6Y-30
X=6Y/4-30/4
X=3Y/2-15/2
