Question 204160
how to solve this question using algebraic formula: There are 26 heads and 74 legs, how many chicken and sheep in the farm?
------------------------
c = # of chickens
s = # of sheep
-----------------
Chickens have 2 legs, sheep have 4. They all have 1 head each.
Legs = 2c + 4s = 74
c + 2s = 37  (divided by 2)
c + s = 26
-------------- Subtract
0c+ s = 11
There are 11 sheep.
26-11 = 15 chickens.
