x = chicken (2 leg) y = goat (4 leg)

25 = x+y

2x+4y = 70

x = 25-y

Conclusion, x/chicken = 15

y/goat = 10

(LOL)

c = chicken

g = goat

25 = c + g......(1)

70 = 2(c) + 4(g)

= 2c + 4g......(2)

When g =25 - c,

(1) - (2), 2c + 4( 25 - c ) = 70

c = 15

When c = 15, 25 = 15 + g

g = 10

Chicken = 15

Goat = 10

Need more time to get the answer!
