comment How to solve this nonlinear 2 by 2 equations?
Seems you forgot to include the a = 0.25; F = 0.015641; q1 = 5.3415; c[b_] := Log[b + 1]; part. It only matters because the OP has defined c[b_] wrong.

@Mr.Wizard I don't know about history, but I'm sure subtlety and humor are healthy and kicking right in front of your computer. Cheers!

@Mr.Wizard In case it wasn't clear enough. I know the vandals quite well en.wikipedia.org/wiki/Vandals#The_turbulent_end :)

Just to clarify: I refused to edit my answer because I think it isn't necessary, but I would NEVER call you a vandal, no matter how you edit my posts.

@Mr.Wizard I think the necessary explanation is already written in the RealDigits[] docs. Feel free to retain your vote.

comment Cannot solve equation
You may start by something like this r = Reduce[eqn[[1]] /. a*(n - o)/n -> x /. {n -> (a o)/(a - x)}, x, Reals]; FullSimplify[r /. x -> a*(n - o)/n, Assumptions -> ao*1/2 < n]
