percent ---------------- quantity
\n" ); document.write( "Alcohol I 22.00% ---------------- x ml
\n" ); document.write( "Alcohol II 9.00% ------ 560 - x ml
\n" ); document.write( "Mixture 17.50% ---------------- 560
\n" ); document.write( "Total 560 ml
\n" ); document.write( "22.00% x + 9.00% ( 560 - x ) = 17.50% * 560
\n" ); document.write( "22 x + 9 ( 560 - x ) = 9800
\n" ); document.write( "22 x + 5040 - 9 x = 9800
\n" ); document.write( "22 x - 9 x = 9800 - -5040
\n" ); document.write( "13 x = 4760
\n" ); document.write( "/ 13
\n" ); document.write( " x = 366.15 ml 22.00% Alcohol I
\n" ); document.write( " 193.85 ml 9.00% Alcohol II
