Tina has 5 cages and 16 parrots.
Putting 4 parrots in a cage (16 parrots/4 cages)) leaves one cage empty. Putting 3 parrots in each case (15 parrots/5 cages) leaves one parrot without a cage.

n = number of cages
p = number of parrots

p = 4(n-1)
p = 3n + 1
3n + 1 = 4(n - 1)
3n + 1 = 4n - 4
5 = n
p = 3 * 5 + 1 = 16
