\n" ); document.write( " $\"+n+=+%283%2F4%29%2A%28+336+-+n+%29+\"$
\n" ); document.write( " $\"+4n+=+3%2A%28+336+-+n+%29+\"$
\n" ); document.write( " $\"+4n+=+1008+-+3n+\"$
\n" ); document.write( " $\"+7n+=+1008+\"$
\n" ); document.write( " $\"+n+=+144+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+336+-+n+=+336+-+144+\"$
