\r\n" );
document.write( "Let n be the number of nickels, the the number of dimes is 26-n.\r\n" );
document.write( "\r\n" );
document.write( "The \"value\" equation is \r\n" );
document.write( "\r\n" );
document.write( "5n + 10*(26-n) = 225.\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve it:\r\n" );
document.write( "\r\n" );
document.write( "5n + 260 - 10n = 225.\r\n" );
document.write( "\r\n" );
document.write( "5n = 260 - 225,\r\n" );
