You can put this solution on YOUR website!
Let $\"n\"$ = the original number
\n" ); document.write( " $\"+2n+%2B+12+=+%281%2F2%29%2An+\"$
\n" ); document.write( "Multiply both sides by $\"2\"$
\n" ); document.write( " $\"+4n+%2B+24+=+n+\"$
\n" ); document.write( "Subtract $\"n\"$ from both sides
\n" ); document.write( " $\"+3n+%2B+24+=+0+\"$
\n" ); document.write( "Subtract $\"24\"$ from both sides
\n" ); document.write( " $\"+3n+=+-24+\"$
\n" ); document.write( "Divide both sides by $\"3\"$
\n" ); document.write( " $\"+n+=+-8+\"$
\n" ); document.write( "the original number was -8
\n" ); document.write( "check:
\n" ); document.write( "double it is -16
\n" ); document.write( "Add 12, and you have -4
\n" ); document.write( "-4 is half of -8
\n" ); document.write( "OK \n" ); document.write( "

\n" );
