Non-linear ecuation...

I have the next set of nine non-linear ecuations:

ln(a)-ln(f)+i+4g+(19720/8314)=0
ln(b)-ln(f)+2g+h-(192420/8314)=0
ln(c)-ln(f)+h+i-(200240/8314)=0
ln(d)-ln(f)+2h+i-(395790/8314)=0
ln(e)-ln(f)+2g=0
a+c+d-2=0
4a+2b+2e-14=0
b+c+2d-3=0
a+b+c+d+e-f=0

Where:
x[1]=a
x[2]=b
x[3]=c
x[4]=d
x[5]=e
x[6]=f
x[7]=g
x[8]=h
x[9]=i

Octave can't solve it... (non-convergent), but in fact i know that set of
ecuations has solution. Because is a Book example. 
Octave can solve it if i put the initial x's [a,b,c,d,e,f,g,h,i] as the
exactly solutions. But that way isn't usefull for me... 
Any sugestions?

Regards from Mexico.
