percent ---------------- quantity
\n" ); document.write( "20 ---------------- x
\n" ); document.write( "50 ---------------- 8-x
\n" ); document.write( "30.00% ---------------- 8 \r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "20x+50(8 -x)=30*8
\n" ); document.write( "20x+400- 50x=240
\n" ); document.write( "20x-50x =240-400
\n" ); document.write( "-30x=-160
\n" ); document.write( "/-30
\n" ); document.write( "x=5.33 20% alcohol
\n" ); document.write( "Balance 2.67 50% alcohol
