Ok ive attempted what i think might be an answer...
x-12
----
3
----
5x+1
----
x

Right?
and then i flip flopped it so i could multiply it..
(x-12) x
------ x -----
3 5x+1
(the x in the middle symbolizes multiplication)
so after i multiply them out i get...
(x^2)-12x
---------
15x +3

so is that the right answer?
