document.write( "Let x represent represent the amount of 10% solution
\n" );
document.write( "Question states*** 
\n" );
document.write( "Mixing together to form (15L+x) 20% solution
\n" );
document.write( " .10x + .40*15L = .20(15L+x)
\n" );
document.write( "Solving for x 
\n" );
document.write( "    .20*15L = .10x
\n" );
document.write( "     .20*15L/.10 = x = 30L, the amount of the 10% solution\r
