Okay, the chickens have 2 feet and the goats have 4. So let’s make the number of chicks C and the number of goats G.
So the number of legs would be 2 x C + 4 x G which is equal to the total number of feet, or 56
2C + 4G = 56
And, we know she has 22 altogether, right? So C + G = 22
Now, you have 2 equations and can solve.
C=22-G
2C + 4G = 56
Or 2 [22-G] + 4G = 56
44-2G+4G=56
44+2G=56
2G=12
G=6
So, the number of goats is 6, and that means the number of chicks has to be 16.

You didn't describe further how will get c=16
G=6
And more is 16+6=22
So 32+24=56
G=6
And more is 16+6=22
So 32+24=56
