Number of cows+number of hens=13
Right?

So the number of hens=13-x

Answer 9

So total legs of all cows=4x

Total legs of all hens=(13-x)*2

x=?

Answer 13

Response plz for better understanding

Answer 14

let no of cows=x
cow has 4 legs so legs of cow=4x
no of chikens=13-x
no of legs of chicken=2(13-x)
total no of legs=36
so
4x+2(13-x)=36
4x+26-2x=36
2x=10
x=5
so no of cows=5
no of chickens=13-5= 8
