Question

Animals and Wheels

Answer 1

Answer:

11 pigs.

6 chickens.

Step-by-step explanation:

Pigs have 4 legs while chickens have 2 legs. Also, pigs have just 1 head and the same for chickens.

Let pigs be X and let chickens be Y

For heads,

X + Y = 17

For legs,

4X + 2Y = 56

Solving both equations simultaneously,

4X + 2(17 - X) = 56

2X = 56 - 34

2X = 22

X = 11

So, Y = 17 - 11

= 6

There are 11 pigs and 6 chickens.
