I've been a degreed mechanical engineer for 35 years and thought I could do algebra in my sleep. But I think I've met my Waterloo. I'm working with a phenomenon with exponential decay and I need to solve the following equation for x:

a log(1 - b/x) = c log(1 - d/x)

a, b, c & d are known parameters. Is this solvable to a general equation of x =_____?
