Let chickens be x and goat be y.
As we know that chicken have two legs and goat have four legs.
2x + 4y = 496.
Total animals = 142 i.e.
x+y = 142

x + y = 142
x = 142 - y ----- (1)
2x + 4y = 196 ---- (2)
Substituting equation (1) on (2)
2(142-y) + 4y = 192
by solving these you will get the value of y then put the value in eqn. (1), you will get the x.
