Quizplus · Accepted Answer

Let the number of dogs be $d$ and the number of chickens be $c$. We have two equations: $d + c = 12$ and $4d + 2c = 28$ (since dogs have 4 legs and chickens have 2 legs). Solving these equations simultaneously, we find that $d = 2$ and $c = 10$, which satisfies the condition that there are at least twice as many chickens as dogs.
