Question 999042
A person have some hens and some cows. Number of head is 38 and number of legs 100 then how many cows and hens.
=======
Heads Equation:: h + c = 38
Legs Equation:: 2h +4c = 100
-------
Modify for elimination:
h + c = 38
h + 2c = 50
----
Subtract and solve for "c"::
c = 12 (# of cows)
----
h = 38-12 = 26 (# of hens)
