Correct answer and explanation

Correct answer: 7

Explanation: āœ… Correct Answer: B) 7 šŸ“š Explanation: Step by step solving: Let the number of cows be C and chickens be H. Total heads = C + H. Total legs = 4C + 2H. According to the problem: 4C + 2H = 2(C + H) + 14. Simplify: 4C + 2H = 2C + 2H + 14. Subtract 2H from both sides: 4C = 2C + 14. 2C = 14, so C = 7. There are 7 cows.
