[Maxima] help on solving an equation containing exponential functions

[Bund Martin]

Hi,

I am looking for a way to do the following:

eqn:U2=(Rn*Ub*%e^B(1/T-1/Tn))/(Rn*%e^B(1/T-1/Tn)+Rv);
solve(eqn, T);

Maxima gives me the result []. However, my collegue says he found a
solution with Mathematica. Can I do something similar with Maxima?

Thanks in advance for your help on this probably simple problem
