Prompt

An aquarium uses small and large tanks to temporarily hold a total of 37 fish. Each small tank holds 1 fish, and each large tank holds 2 fish. Which equation represents this situation, where

s

is the number of small tanks and

b

is the number of large tanks the aquarium uses?

s + 2 b = 37

s + b = 37

2 s + b = 37

2 s + 2 b = 37
