Peter,

It would not be particularly complicated.  There is a well documented
method called Gaussian Elimination which can be applied to an array of
the coefficients of the equations, which results in successive coefficients
being reduced to zero, until only one non-zero coefficient remains in the
last row. That provides a value for that unknown. The previous row represents
an equation of just two unknowns, one of which is the one already found,
and therefore you can find the second unknown. Each predeceding row contains
one more unknown over what you already know and therfore it can be found.
Thus working backwards, you can ultimately find all unknowns.  The
method is methodical and predictable and quite amenable to being programmed.

John.
