title: Overdetermined equation system in Maxima
body: <p>I have an equation system that seems to be overdetermined:</p>
  
  <pre><code>eq1:q = 34000*(T[CuH2O]-30);
  eq2:q = 380*(T[NiCu]-T[CuH2O])/(0.20e-1);
  eq3:q = 70*(T[WNi]-T[NiCu])/(0.5e-2);
  eq4:q = 10*(T[SlW]-T[WNi])/(0.4e-3);
  eq5:q = 1.5*(T[StSl]-T[SlW])/(0.1e-2);
  eq6:q = 30*(1520-T[StSl])/(0.2e-2);
  solve([eq1,eq2,eq3,eq4,eq5,eq6]);
  </code></pre>
  
  <p>I used the q value for convenience and Maple solves this without problems. Maxima tells me: <code>solve: more equations than unknowns.</code></p>
  
  <p>Is there any way to solve this? </p>
