i need a graph so i can see then i will solve it
Yes its correct you did well :)
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).

4y = 36
y = 36/4
y = 9
