Answer: There are 19 cats and 38 dogs.
Explanation:
Given, A veterinarian clinic, there are twice as many dogs as there cats.
Let x = Number of cats
then, number of dogs = 2x
Since , total number of dogs and cats = 57
So, x+ 2x= 57

Divide both sides by 3 , we get


Number of cats =19
then, number of dogs = 2(19) = 38
hence, there are 19 cats and 38 dogs.
