\n" ); document.write( "Equations:
\n" ); document.write( "x + y + z = 123
\n" ); document.write( "y = 2x-9
\n" ); document.write( "z = 3x+6
\n" ); document.write( "----------------------------
\n" ); document.write( "x + y + z = 123
\n" ); document.write( "2x - y + 0 = 9
\n" ); document.write( "3x + 0 - z = -6
\n" ); document.write( "----------------------------
\n" ); document.write( "Solve by any method you know to get:
\n" ); document.write( "x = 21
\n" ); document.write( "y = 33
