\r\n" );
document.write( " = 0.5    <<<---===  it is the \"concentration\" equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2 + x = 0.5*(10+x)\r\n" );
document.write( "\r\n" );
document.write( "2 + x = 5 + 0.5x\r\n" );
document.write( "\r\n" );
document.write( "x - 0.5x = 5 - 2\r\n" );
document.write( "\r\n" );
document.write( "0.5x = 3  ====>  x =  = 6.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  6 liters of the pure concentrate should be added.\r\n" );
