Math Help - rearrange exponential formula

1. rearrange exponential formula

Hi,

I'm trying to rearrange this formula :

y = x*((1-(0.92^((x/2-120)/10+1)))/0.08)

to make x the subject ie. x = ...

Can someone show me how I can do this?

You might be able to rewrite it so that you could solve it in terms of "Lambert's W function" which is defined as the inverse function to $f(x)= xe^x$.
