Question

Please help!
A farmer has dogs and chickens running around in his backyard. There are a total of 36 animals, and the farmer counts a total of 56 legs. The farmer can use a system of equations to determine how many of each animal there are. He claims that one of the equations in the system is 4d+2c=56.Which statement describes the accuracy of the farmer's claim?
It is incorrect because there are 36 animals total, so 4d+2c=36.
It is incorrect because there are 56 legs total, so d+c=56.
It is correct because there are 56 legs total, so 4d+2c=56.
It is incorrect because there are 36 animals total, so d−c

@jigglypuff314 Hello again, I'm stuck with this problem and if you can right now do you mind helping me understand it? Thanks!

Answer 2

They only want to ask us about that one equation right?

The idea behind it is:
(number of feet on a dog)times(number of dogs) + (number of feet on a chicken)times(number of chicken) = (total number of feet)
