underdetermind equations

hi,
If posted this on another site, but I wondered if anyone here can help me. If I had an underdetermind set of simultanous equations, to take a simple example:
x + 2y = 10
y - z = 2
Is there a way of predicting the number of possible solutions for x,y and z? Or a numerical method for finding a possible solution?
I have a complex linear system with around over 60 variables, and I can produce 27 simulateous equations that are always true for my system This is the ultimate undetermind system!!
Other than doing a trial and error brute force-type search, is there an area of maths that deals with such a problem? Is there a way of defining a search space, and at least predicting where a possible solution would lie?
thank you very much for your help
Austin
