Let x = don
\n" ); document.write( "Since Marcus practiced 3 hours longer than don he is x + 3 \r
\n" ); document.write( "\n" ); document.write( "Combined they practiced 11 hours = x + x + 3 \r
\n" ); document.write( "\n" ); document.write( "so 2x + 3 = 11; 2x = 8; x = 4 \r
\n" ); document.write( "\n" ); document.write( "So Don practiced 4 hours and Marcus practiced 7. \r
\n" ); document.write( "\n" ); document.write( "QED
\n" ); document.write( "
