The Reptile House at the zoo has 5 fewer animals than 3 times the number of animals housed in the Rain Forest exhibit. If the Reptile House has 16 animals, how many are in the Rain Forest exhibit?
Define a variable ** Let x be the number of animals in the Rain Forest exhibit
Write an equation ** 3x-5=16
Simplify ** 3x=21
Divide by 3 ** x=<<7=7>>7
