1. Answer:

   Let no. of hens be x and no. of cows be y. For heads the equation is

   x + y = 50 (head count is 50)

   For legs the equation is

   2x + 4y =144 (2 legs of hen and 4 legs of cow assuming that none are missing any limbs)

   From head count equation

   y = 50 – x

   substituting this in leg count equation we get

   2x + 4(50 – x) = 144

   2x + 200 – 4x = 144

   -2x = 144 – 200

   -2x = – 56

   x = 28

   Substituting in headcount equation we get

   y = 50 – 28

   So y = 22

   So there are 28 hens and 22 cows on the farm
