Can you explain how to solve this math problem: Together Lily, David, and Bodhi collected 43 insects. Lily found 7 more than David. David found half of what Bodhi found. How many insects did Lily find?
Let B = the number of insects Bodhi collected
David = B/2
Lily = B/2 + 7
B + B + 7 = 43
2B = 36
B = 18 insects
David = 18/2 = 9 insects
Lily = 9 + 7 = 16 insects
Lily found 16 insects.
