\r\n" );
document.write( "Let x = # of nickels.\r\n" );
document.write( "Then the number of quarters is (20-x).\r\n" );
document.write( "\r\n" );
document.write( "The nickels contribute 5x to the total.\r\n" );
document.write( "The quarters contribute 25(20-x) to the total.\r\n" );
document.write( "\r\n" );
document.write( "The \"value\" equation is \r\n" );
document.write( "\r\n" );
document.write( "5x + 25(20-x) = 340   (cents).\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve:\r\n" );
document.write( "\r\n" );
document.write( "5x + 500 - 25x = 340  --->  -20x = 340 - 500 = -160  --->  x =  = 8.\r\n" );
