You can put this solution on YOUR website!
7x - 3y + 2z = 0
\n" ); document.write( "4x - 4y - z = 2
\n" ); document.write( "5x + 2y + 3z = 1
\n" ); document.write( "----------
\n" ); document.write( "Using matrix methods the solution is:
\n" ); document.write( "x=1,y=1,z=-2
\n" ); document.write( "-------------
