---------percent ---------percent ---------------- quantity
\n" ); document.write( "Alcohol I 30 ---------------- x quarts
\n" ); document.write( "Alcohol II 70 ---------------- 60 - x quarts
\n" ); document.write( "Mixture 50.00% ---------------- 60
\n" ); document.write( "
\n" ); document.write( "30 x + 70 ( 60 - x ) = 50 * 60
\n" ); document.write( "
\n" ); document.write( "30x+4200-70x=3000
\n" ); document.write( "30x-70x =3000 -4200
\n" ); document.write( "-40 x = -1200
\n" ); document.write( "/ -40
\n" ); document.write( " x = 30 quarts 30.00% Alcohol I
\n" ); document.write( " 30 quarts 70.00% Alcohol II
