16 = snakes + guinea pigs + miniature poodles

s=snakes, g=guinea pigs, m=miniature poodles

16 = s + g + m

g = 1 + m

s = 2 + g

So:

16 = (2 + g) + (1 + m) + m

16 = 2 + (1 + m) + (1 + m) + m

Combine like terms:

16 = 4 + 3m

12 = 3m

4 = m

Since g = 1 + m:

g = 5

Since s = 2 + g:

s = 7

so the shop has 7 snakes
