# Homework Help: Finding x

### Toby_Obie

Hello

I originally posted this on the pre-calculus board, but no answer

Im trying to rearrange to find x from the below (all other values, A, b and c known)

$$A = bx / 1-(1+x)^{-c}$$

I've rearranged but to no avail, I'm unsure how to isolate x

Thanks, much appreciated

Is it A=(b*x)/(1-(1+x)-c) ?
