maybe this information would be helpful to me, and to others also who have more expertise.

Sure. It's real easy.

If that's not the answer you were expecting then how about specifying which variable you want to solve for.

i guess natski already stated that he wants to solve for x.

Whoops, that will teach me to read all of the post and not skip the last line.

Sorry, that'ss a transcendental equation in x, so there will be no closed form solution.

Oh yeah it's not transcendental in x. If y is an integer it's a polynomial in x.

So I was hoping for a neater algebraic solution.

Well there might be some partiucular values of "y" for which it can work, but in general I don't think it's going to be possible.
