There a 46 legs in the exhibit in the zoo. there are 2 more 2 legged animals than 4 legged animals. How many of each are there?

Question

That is about it.  I am wondering about how to solve.

Answer 1

Let x be the number of 4 legged animals. That means there are x+2 two-legged animals.
The total number of legs = 4x + 2(x+2) = 46

Now, we distribute the 2:

4x+ 2x + 4 = 46

6x + 4 = 46

6x = 42

x = 7

So, there are 7 four-legged animals and 9 two-legged animals.
