A man has some hens and cows. If the number of heads be 48 and the number of feet equals 140, then the number of hens will be:



Consider the hen be x and cow be y
   all the hen and cows have only one head
       then x+y=48 named as equation 1
     hen have 2 feet and the cow have 4 feet
     then 2x+4y=140 named as equation 2
     solve 1 and 2nd equation
  2nd equ as                          2x+4y=140
1st equ multiply as 2 then      2x+2y=96
   subtract 2 equ                   --------------
                                                 y=22  (cow = 22)
                           then x+y=48
                                 then x=24 (hen = 24)
