document.write( "where \"n\" is the number of nickels.\r\n" );
document.write( "\r\n" );
document.write( "Solve for n:\r\n" );
document.write( "\r\n" );
document.write( "5n + 1400 - 25n = 500,\r\n" );
document.write( "\r\n" );
document.write( "-20n = 500 - 1400,\r\n" );
document.write( "\r\n" );
document.write( "-20n = -900  --->  n =  = 45.\r\n" );
document.write( "\r\n" );
document.write( "The number of nickels is 45, the number of quarters is 56-45 = 11.\r\n" );
