Answer:
x = 2

Let and be the number of elves and reindeers, respectively.
We know that:
(so far 14 of them have arrived)
(each reindeer has 4 legs and each elf has two)
If we multiply the first equation by 2 we have , and if we subtract this equation from the second we have which implies .
So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
