If evaporating x pounds of water,
\n" ); document.write( "\"%2812%2A80%29%2F%2880-x%29=20\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%2880-x%29%2F%2812%2A80%29=1%2F20\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"80-x=%2812%2A80%29%2F20=12%2A4=48\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"80-x=48\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=80-48\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight%28x=32%29\"
