Question

Anton counted 36 dogs and cats at the animal shelter. He noticed that there are 18 fewer cats than dogs. If c= the number of cats and d= the number of dogs, then which system of equations represents the situation?

Answer 1

Answer: 2d + 18 = 36

Explanation:

c = number of cats, d = number of dogs

1. d + c = 36 because there are 36 cats and dogs combined

2. c = d - 18 because there are 18 fewer cats than dogs

3. d + d - 18 = 36 because we inserted the equation of step 2 in the equation of step 1

4. 2d + 18 = 36 is the simplified equation of step 3
