You have a little 'oopsie' right at the beginning.

When you distribute the -5 across (x - 6) you should get -5x + 30 (minus times minus is plus).

So your next step is:



So the step after that is:



Then you went on trying to collect like terms with the variable, but you just dropped a 5x somewhere.

I would first combine the 3x - 5x in the RHS.



Then add 2x to both sides



Finally, divide both sides by 14 leaving you with an irreducible improper fraction that, although quite correct, is uglier than a mud fence.

Write back if you need help with the set builder notation part.
