Question 150790
Like this you mean?
{{{3x/(x-1)+(6x-9)/(x-1)-6=0}}}
{{{(3x+(6x-9))/(x-1)=6}}}
{{{(9x-9)/(x-1)=6}}}
{{{9(x-1)/(x-1)=6}}}
{{{9=6}}}
No solution, there is no x that solves this problem.

If my assumption about the equation setup was incorrect, please re-post the question. 

Use parentheses to isolate numerators and denominators in fractions.
Good luck!
