\n" ); document.write( "x +y-3z=-6
\n" ); document.write( "===============
\n" ); document.write( "x-2y+3z=6 Eqn 1
\n" ); document.write( "-x+y +z=4 Eqn 2
\n" ); document.write( "----------------------- Add
\n" ); document.write( "-y + 4z = 10 Eqn A
\n" ); document.write( "========================
\n" ); document.write( "-x+y +z=4 Eqn 2
\n" ); document.write( "x +y-3z=-6 Eqn 3
\n" ); document.write( "----------------------- Add
\n" ); document.write( "2y - 2z = -2 --> y - z = -1 Eqn B
