Thank you shoonya!
A generalisation like expanding to 6*6 or more is not quite trivial, so I was (still am) hoping to find something already tested and cleared. But if nothing turns up, I guess I have to go the hard way via Cramer's rule. Or maybe translate some suitable routines from LAPACK (probably better).

No, A is a matrix with 6 rows and 6 columns!

A linear system of eq:s, i.e.
Ax + b=0
where A is a n*n matrix, x is a n-dimensional vector of unknown and b is a n-dim. constant vector.
n=6 in the actual case, could be 7 or more tomorrow.
A mathematics library in PHP (something like LAPACK in Fortran) is too much to wish for, but maybe someone has translated something ...?

Solving system of equations
I need to solve a system of eq:s with 6 unknown on line (in a trim routine for a simulation model). Do you happen to know where I can find a good function that does that?
