Question

one day at the village veterinary practice the doctors treated twice as many dogs as cats if they treated a total of 51 cats and dogs how many of each did the doctors see?

Answer 1

First, turn this into an equation.

This is what we know:

The doctors treated twice as many dogs as cats and a total of 51 cats and dogs were treated.

We will let X be cats.

2X + X = 51. Solve for X

3X = 51

X = 17

Dogs: 2X = 2(17) = 34

Cats: X = 17
