**this is from a Diff EQ but but its just algebra i think??**

I'm just working through an example here and its say to solve the equation

(y/k)=(ynot/k)/((ynot/k)-[1(ynot/k]e^(-rt))

for t. then in the next line it shows it solved for

e^(-rt)={(ynot/k)(1-(y/k)}/{(y/k)(1-(ynot/k)}

now i have been trying to fihure this out for awhile and its frustrating me, and i just can't seem to move on until i understand what I am not doing. can someone show me the steps involved in solving for e^(-rt) before i thrash this book or also recommend a program that will show algebraic steps in solving equation so that i don't have to spend hours figuring my retarted math mistakes out.
