syntax:

(If you are feeling lazy then the braces can be omitted.)

<lineq\_list> :- linear equations. Can be of the form equation = number or just equation.

coeff_matrixcreates the coefficient matrix C of the linear equations.

It returns {C,X,B} such that CX = B.

examples:

coeff_matrix({x+y+4*z=10,y+x-z=20,x+y+4});
