Let $\"+x+\"$ = ml of water to be added
\n" ); document.write( " $\"+.13%2A24+=+3.12+\"$ ml of alcohol in 24% solution
\n" ); document.write( "--------------
\n" ); document.write( " $\"+3.12+%2F+%28+x+%2B+24+%29+=+.12+\"$
\n" ); document.write( " $\"+3.12+=+.12%2A%28+x+%2B+24+%29+\"$
\n" ); document.write( " $\"+3.12+=+.12x+%2B+2.88+\"$
\n" ); document.write( " $\"+.12x+=+3.12+-+2.88+\"$
\n" ); document.write( " $\"+.12x+=+.24+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( "2 ml of water needs to be added
