You can put this solution on YOUR website!
sam = mary /2
bill = mary / 3
sam + bill + mary = 44
mary+%2F+2+%2B+mary+%2F+3+%2B+mary+=+44
%283%2Amary+%2B+2%2Amary+%2B+6%2Amary%29+%2F+6+=+44
11%2Amary+%2F+6+=+44
11%2Amary+=+44+%2A+6
mary+=+%2844+%2A+6%29+%2F+11+=+4+%2A+6+=+24
Therefore sam = mary / 2 = 24 / 2 = 12 years
