\r\n" );
document.write( "Let x be the number of downloads of the high-quality version.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of downloads of the other version was 1540-x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Write the total volume of downloaded megabytes\r\n" );
document.write( "\r\n" );
document.write( "    4.7x + 2.7*(1540-x) = 5478   megabytes.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and find x\r\n" );
