Answer:
Let r→Rabbits
p→pheasants
Total number of heads=35
r+p=35
Total number of feet=98
Rabbits have 4 and pheasants have 2
So,
4r+2p=98
r+p=35
Multiply 2 on both sides,
2r+2p=70-------(1)
4r+2p=98------(2)
(2)-(1)
4r+2p=98
2r+2p=70
________
2r+0=28
r=28/2
r=14
Therefore, there are 14 rabbits.
No.of pheasants=35-14
=21
