Usually, people have 2 legs and dogs have 4.

39(2) + 4X = 124

78 + 4X = 124

4X = 46

X = 11.5

If your data are correct, there must have been one two-legged dog or a dog with six legs. (Maybe there might have been two dogs with 5 legs each! Another possibility is that two of the people were amputees!) Check your original numbers.

I hope this helps. Thanks for asking.
