document.write( "Let x be the volume of the 3% elixir to mix / (to add), in milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you have this equation for the pure elixir amount before and after the mixing\r\n" );

document.write( "\r\n" );
document.write( "    0.03x + 0.09*10 = 0.05(x+10).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );

document.write( "    x = \"%280.05%2A10+-+0.09%2A10%29%2F%280.03-0.05%29\" = 20.\r\n" );

document.write( "CHECK.  I will check the concentration  \"%280.03%2A20%2B0.09%2A10%29%2F%2820%2B10%29\" = 0.05 = 5%.    ! Precisely correct !\r\n" );
