assistant
Define a variable ** Let B = the number of insects Bodhi collected
How many insects did David collect? ** David = B/2
How many insects did Lily collect? ** Lily = B/2 + 7
Write an equation ** B + B + 7 = 43
Simplify ** 2B = <<36=36>>36
Simplify ** B = <<18=18>>18 insects
How many insects did David collect? ** David = 18/2 = <<18/2=9>>9 insects
How many insects did Lily collect? ** Lily = 9 + 7 = <<9+7=16>>16 insects
How many insects did Lily collect? ** Lily found <<16=16>>16 insects.
