Ana saw some kitten and baby chicks for sale when she went to the pet store. altogether she counted 16 heads and 46 legs. how many of each did ana see at the pet store?
+36916 Assuming there are no birth defects
kittens have 4 legs and 1 head 4k and k is kitten heads
Chickens have 2 legs 2c = chicken legs c = chicken heads
4k + 2c = 46
k+c = 16 two equations and two unknowns
Multiply second equation by -2
-2k - 2c = -32 and add it to the forst equation
to get
2k = 14
k = 7 then k+ c = 16 means c = 9
