your equation makes the implicit assumption that the amounts of both mixtures are equal (you used the same quantity, x)
\n" ); document.write( "___ this is not necessarily true\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "try this ___ x(.11) + (500 - x)(.16) = (500)(.13) \n" ); document.write( "

\n" );
