This is a system of 12 variables and 10 equations. Looks like there will be 
more than one solution (if I remember my 8th grade algebra--its beginning to 
get very foggy). Given a proper set of linear equations, I think numarray and 
scientific python have very convenient tools for this. An introductory linear 
algebra book can provide everything you need to know about this topic.
