Answer:

y = 100

Readme [11.4K]

Answer:

47 ducks and 7 cows

Step-by-step explanation:

Ducks have 2 legs and cows have 4 legs.

If all the animals are ducks,

number of legs= 54(2)= 108

Difference in number of legs= 122 -108= 14

Difference in no. of legs per animal= 4 -2 = 2

Number of cows=14 ÷2 = 7

Number of ducks= 54-7= 47

Thus, he have 47 ducks and 7 cows.

Let's check:

Total number of feet= 7(4)+ 47(2) = 122 ✓

You could also first assume that all the animals are cows. The answer would be the same.
