Answer 1

Let

x -----> the number of cows

y -----> the number of chickens

we know that

x+y=100 --------> equation A

4x+2y=286 ------> equation B

Remember that, a cow has 4 legs and a chicken has two legs

solve the system of equations

Using a graphing tool

solve the system of equation by graphing
