Let $\"+w+\"$ = ml of water to be added
\n" ); document.write( " $\"+100+%2F+%28+100+%2B+w+%29+=+.2+\"$
\n" ); document.write( " $\"+100+=+.2%2A%28+100+%2B+w+%29+\"$
\n" ); document.write( " $\"+100+=+20+%2B+.2w+\"$
\n" ); document.write( " $\"+.2w+=+80+\"$
\n" ); document.write( " $\"+w+=+400+\"$
\n" ); document.write( "400 ml of water must be added
