Transposition of LN equation

[frogboy]

Hi, I would like to transpose the following formula to find x, if some one could please help? thanks

y=-41.12ln(x)+330.21

I will solve this for you. y = aln(x) - c
y+c =aln(x)
(y+c)/a = ln(x)

x= e^[(y+c)/a]

Thanks Jomo, what is e^x in excel? sorry I would like to put this into excel so unsure of the functions? cheers
