\n" );
document.write( "Hi,
\n" );
document.write( "Let x represent the amount of the 8% solution, 
\n" );
document.write( "then (1L-x) would be the amount of the 6% solution
\n" );
document.write( ".08x + .06(lL -x) = .064*1L
\n" );
document.write( "solving for x
\n" );
document.write( ".08x + .06*1L - .06x = .064*1L
\n" );
document.write( ".02x = .004L
\n" );
document.write( "x = .2L of the the 8% solution and .8L of the 6% solution   (1L-.2L)\r
\n" );
document.write( "\n" );
document.write( " \n" );
