Solving equations



Hello,

I have maxima 5.20.1 thanks to help from this mailing list ;)

How to make maxima give me some meaningful result in the following:

eq1: I/(e*V) - Nw*(1-h)/t_w2 + NQ*h/t_2w - Nw/t_wR=0;
eq2: Nw*(1-h)/t_w2 - NQ*h/t_2w + NQ*h*(1-f)/t_21 + NQ*f*(1-h)/t_12=0;
eq3: NQ*h*(1-f)/t_21 - NQ*f*(1-h)/t_12 - NQ*f*f/t_1R - g*P/(sigma*hbar*omega)=0;
eq4: g = gmax*(2*f-1);

Nw, h, f are variables, the rest are real numbers. How to solve these
eqs to get the expression of Nw, h and f? Thanks in advance.
