sam = mary /2
\n" ); document.write( "bill = mary / 3
\n" ); document.write( "sam + bill + mary = 44
\n" ); document.write( " $\"mary+%2F+2+%2B+mary+%2F+3+%2B+mary+=+44\"$
\n" ); document.write( " $\"%283%2Amary+%2B+2%2Amary+%2B+6%2Amary%29+%2F+6+=+44\"$
\n" ); document.write( " $\"11%2Amary+%2F+6+=+44\"$
\n" ); document.write( " $\"11%2Amary+=+44+%2A+6\"$
\n" ); document.write( " $\"mary+=+%2844+%2A+6%29+%2F+11+=+4+%2A+6+=+24\"$
\n" ); document.write( "Therefore sam = mary / 2 = 24 / 2 = 12 years \n" ); document.write( "
