\n" );
document.write( "Let x represent the amount of the more concentrated 60% solution, 
\n" );
document.write( "then (100L - x) would be the amount of the 30% solution
\n" );
document.write( "Mixing together to form the 100L of 45% solution***
\n" );
document.write( ".60x + .30(100L-x) = .45*100L
\n" );
document.write( "Solving for x
\n" );
document.write( ".30x = .15*100L
\n" );
document.write( "x = 50 L, the amount of the more concentrated 60% solution.  50L of the 30% also
