how much water should be added to 28 milliliters of 17% alcohol solution to reduce the concentration to 14%?

\r\n" );
document.write( "In the beginning, 17% of the 28 milliliters of liquid, which is 4.76\r\n" );
document.write( "milliliters, is pure alcohol.  The rest is water.\r\n" );
document.write( "\r\n" );
document.write( "Then we add x milliliters of water.\r\n" );
document.write( "\r\n" );
document.write( "Now we have 28+x milliliters of liquid of which the 4.76 milliliters \r\n" );
document.write( "of pure ancohol is now only 14% of.  So,\r\n" );
document.write( "\r\n" );
document.write( "The 4.76 ml. of pure alcohol = 14% of the 28+x milliliters of liquid.\r\n" );
document.write( "\r\n" );
document.write( "   4.76 = .14(28 + x)\r\n" );
document.write( "\r\n" );
document.write( "Solve that and get x=6 as the number of milliliters of water to add.\r\n" );
