## Main Question or Discussion Point

How do I calculate t from the following equation?

z=a+b(e^k*t -1)

Guess this should be right to start with:

t=ln(z/b)

but what to do with the a and -1? and how do I calculate ln(z/b)? as lnz/lnb? I've tried thinking (didn't work *smirk*) and trial and error with simple numers (didn't work either)

thanks a lot!
