x + y = 20
\n" ); document.write( "So, y = 20-x
\n" ); document.write( "And,
\n" ); document.write( ".30x + .10y = (20)(.19)
\n" ); document.write( ".30x + .10 (20-x) = 3.8
\n" ); document.write( ".30x + 2 - .10x = 3.8
\n" ); document.write( ".30x - .10x = 3.8 - 2
\n" ); document.write( ".20x=1.8
\n" ); document.write( "x=1.8/.20
\n" ); document.write( "x=9 liters at 30%
\n" ); document.write( "So,
\n" ); document.write( "x+y=20
\n" ); document.write( "9+y=20
\n" ); document.write( "y=20-9
\n" ); document.write( "y=11 liters at 10%
\n" ); document.write( "
\n" );
