Dear folks--

I'm sure this is a very simple problem, but I have been wrestling with it for two hours without making any progress at all. Help!

I am trying to solve for the tail index of a Pareto distribution. Call it x. I have the mean divided by the lower bound. Call it c.

I know that x/(x-1) = c. So how do I express x in terms of c?

Just the answer would be great, but it would be even better if there was some technique I could learn to solve problems resembling this one.

Thanks! --Beanxx
