[Maxima] Trouble in Solving Equation

Dear All,
I am not very much into Maxima, but I am using it to do some symbolic manipulations.
Please have a look at the small snippet below

assume (N>1000);
assume (df>1);
assume (b<0);
assume (kf>1);
assume (a>0);
Rg:(N/kf)^(1/df);
Rm:0.512*(1-1/log(2*N))*Rg+0.72*N^0.413;
Req:N^(1/3);

phi:N/Rgeo^3;
Rm/Rgeo: a*Rg/Rgeo+b;
myeq: Rm/Rgeo = c*Rg/Rgeo+d;

solve(myeq, Rgeo);

but then maxima does not return the solution for the equation which, to be honest, does not look so terrible.
Am I making some mistake?
Any suggestion is welcome.
Many thanks

Lorenzo
