System of linear equations pdf.

By a system of linear equations we mean a finite set of linear equations in finitely many indeterminates. For instance, the following is a system of two linear equations: 2x+3 y +4 z = 5 x+y +z = 2 . (2.4) By a solution of this system we mean a solution of the first equation which is also a solution of the second equation.
