Answer 1

20 Cows & 15 Birds  if there are total 35 heads and 110 legs

Step-by-step explanation:

Let say number of cows = C

and number of Birds = B

Cow & Birds Have one Head Each

=> C + B = 35    Eq1

Cow has 4 legs & Birds has 2 Legs

=> 4C  + 2B  = 110   Eq2

Eq2 - 2 * Eq1

=> 2C  = 40

=> C = 20

    B = 15

20 Cows & 15 Birds

Answer 2

Answer:

c+ B=35

4C+2B=110

2C=40

C=20

B=15
