What do you really have?
y+2/3=2y-12/3y-9
Not very likely that.

y%2B2%2F3=2y-12%2F3y-9----what you WROTE if rendered.

y%2B2%2F3=%282y-12%29%2F%283y-9%29---------maybe what you meant.


Or is it really this?
%28y%2B2%29%2F3=%282y-12%29%2F%283y-9%29
-
%28y%2B2%29%283y-9%29=3%282y-12%29
3y%5E2%2B6y-9y-18=6y-36
3y%5E2-9y-18=-36
y%5E2-3y-6=-12
y%5E2-3y%2B6=0

y=%283%2B-+sqrt%289-4%2A6%29%29%2F2
y=%283%2B-+sqrt%28-15%29%29%2F2
highlight%28y=3%2F2%2B-+i%2Asqrt%2815%29%2F2%29
