Answer 1

Explanation:

Let

Hens = H

Cows = C

H + C = 48 ...................(1)

2×H + 4×C = 140...............(2)

solving (1) and (2) by substitution method

from (2)

2 H + 4 (48 - H) = 140

-2H + 192 = 140

- 2H = - 52

H = 26

from (1)

C = 48 - H

= 48 - 26

= 22

Answer 2

Answer:

hi follow me , ans

Explanation:

hen and cow has one head each

1 hen two legs

1 cow four legs

total hen + cows = 48

take cow as X

and hen as 48-X

4X + 2(48-X) = 140

4x + 96 - 2x = 140

2x = 140 - 96

2x = 44

x = 22 cows

hen = 26

verifying

22 × 4 =88 cow legs

26 × 2 = 52 hen legs

total legs = 140
