Let $\"+w+\"$ = ml of water to be added
\n" ); document.write( "given:
\n" ); document.write( " $\"+.16%2A24+=+3.84+\"$ ml alcohol in 16% solution
\n" ); document.write( "----------------
\n" ); document.write( " $\"+3.84+%2F+%28+w+%2B+24+%29+=+.12+\"$
\n" ); document.write( " $\"+3.84+=+.12%2A%28+w+%2B+24+%29+\"$
\n" ); document.write( " $\"+3.84+=+.12w+%2B+2.88+\"$
\n" ); document.write( " $\"+.12w+=+3.84+-+2.88+\"$
\n" ); document.write( " $\"+.12w+=+.96+\"$
\n" ); document.write( " $\"+w+=+8+\"$
\n" ); document.write( "8 ml of water must be added
\n" ); document.write( "check:
\n" ); document.write( " $\"+3.84+%2F+%28+w+%2B+24+%29+=+.12+\"$
\n" ); document.write( " $\"+3.84+%2F+%28+8+%2B+24+%29+=+.12+\"$
\n" ); document.write( " $\"+3.84+%2F+32+=+.12+\"$
\n" ); document.write( " $\"+3.84+=+3.84+\"$
\n" ); document.write( "OK \n" ); document.write( "
