You can put this solution on YOUR website!
x + y + z = 30
\n" ); document.write( "xyz = 640.
\n" ); document.write( "find x, y and z
\n" ); document.write( ":
\n" ); document.write( "Use the try and see method
\n" ); document.write( "Prime factor 640, 2*2*2*2*2*2*2*5
\n" ); document.write( "We know all the factors are less than 30
\n" ); document.write( "16 * 4 * 10 seems to work
\n" ); document.write( "x = 4
\n" ); document.write( "y = 10
\n" ); document.write( "z = 16 \n" ); document.write( "

\n" );
