\n" ); document.write( "Let x = amount (liters) of pure alcohol added
\n" ); document.write( "then
\n" ); document.write( "x + .40(6) = .60(x+6)
\n" ); document.write( "x + 2.4 = .60x+3.6
\n" ); document.write( ".40x + 2.4 = 3.6
\n" ); document.write( ".40x = 1.2
\n" ); document.write( "x = 3 litres
