Solve an equation as a fraqtion. Is it possible?

[blevita]

Hi

I would like to solve a simple equation to two variables.
This is obvious a very simple task for the attached example but as you could imagine, i would like to do the same with much more complex equations.

So my question is, is it possible to solve such an equation to a fraqtion which consists of two variables?
I have tried with solve(...,[x/b]) but i got only an empty result.


If the prime is not able to do so, is there any othe tool out there who can do such a algebraic operation?

Thanks
