\n" ); document.write( " Alcohol II30 ---------------- 8 - x liters
\n" ); document.write( " Mixture 40.00% ---------------- 8
\n" ); document.write( "
\n" ); document.write( " 70x+30(8-x)=40*8
\n" ); document.write( "
\n" ); document.write( " 70x+240- 30x=320
\n" ); document.write( " 70x-30x= 320-240
\n" ); document.write( " 40x=80
\n" ); document.write( " /40
\n" ); document.write( " x=2 liters 70.00% Alcohol I
