I'm trying to solve for an exit temprature in a forced air heat
exchanger and I have a total of 7 equations and also 7 unknowns.  I'm
not sure how to go about it by using mathematica to solve these
equatins.  So far I have typed in the equations on a new mathematica
document and have also declared some of the known varialbes.  After
I'm done typing them in I press Shift + Enter and the results that
come out are very confusing (I do no think it is giving me a proper
answer).  Is there a specific path that I must follow to selve for
these equations?
