x +5z=0
\n" ); document.write( "5x+y =0
\n" ); document.write( "y-3z=0
\n" ); document.write( "-------
\n" ); document.write( "x + 0 + 5z = 0
\n" ); document.write( "5x+ y + 0 = 0
\n" ); document.write( "0 + y - 3z = 0
\n" ); document.write( "------
\n" ); document.write( "Subtract 5 times row1 from row2 to get:
\n" ); document.write( "x + 0 + 5z = 0
\n" ); document.write( "0 + y - 25z= 0
\n" ); document.write( "0 + y - 3z = 0
\n" ); document.write( "-----
\n" ); document.write( "Subtract 2nd row from 3rd row to get:
\n" ); document.write( "x + 0 + 5z = 0
\n" ); document.write( "0 + y - 25z= 0
\n" ); document.write( "0 + 0 + 22z = 0
