If you are ADDING WATER to dilute the mixture, then
\n" ); document.write( "letting x = # of quarts water that had to be added, we get
\n" ); document.write( "0.65*18 + x = 0.80(x+18),
\n" ); document.write( "11.7 + x = 0.80x + 14.4,
\n" ); document.write( "0.20x = 2.7,
\n" ); document.write( "x = 13.5, # of quarts water that had to be added.
\n" ); document.write( "
\n" );
