Question 697332
For this question, you can set up a system of two equations with two variables.

Let p = the number of pigs and t = the number of turkeys.

We know there are 66 animals total, so

p + t = 66

We also know there are 210 feet. Pigs have 4 feet and turkeys have 2, so the second equation is:

4*p + 2*t = 210

Given these equations, you can solve for either p or t first by eliminating the other variable. 

Since p + t = 66, subtract p from both sides to get

t = 66 - p. Next, replace the variable t in the second equation with 66 - p, since t = 66 - p:

4*p + 2*(66 - p) = 210
4*p + 132 - 2*p = 210
2*p = 78
p = 39

So, there are 39 pigs. Plug this value for p into either equation to find t:

39 + t = 66
t = 27

Thus, there are 39 pigs and 27 turkeys.
