Would that look like
(3)/(4x-9) = 27? If so, you can multiply both sides by (4x-9) to cancel the 4x-9 on the bottom and get it onto the other side. It would look like this:
(4x-9)/(1) * (3)/(4x-9)= 27 * (4x-9)/(1) \\  3 = 27(4x-9).

Distribute the 27 to the 4x and -9, which will get you this:
3=108x-243.

Then you want to add the 243 on both sides to isolate the x which should get you this:
246=108x.

Your next to final step is to divide both sides by 108 to leave the x alone. This will appear like this:
x= (246)/(108).

Your last step is to simplify the fraction or convert it into a decimal depending on which you prefer. If simplified, you should get
x=13(2)/(3) and for a decimal you will get
x=13.67
