There are 172 South American animals in the Springdale zoo that is 45 more than half of the African animals in the zoo write an equation you could use to find n the number of African animals in the zoo

This situation can be written as (where x is the number of African animals):

172 = 1/2 * x + 45
172 = 1/2x + 45             / - 45 (both sides)
127 = 1/2x                    / * 2 (both sides)
x = 254

Doublecheck:

172 = 1/2 * 254 + 45
172 = 127 + 45
172 = 172

So it's correct :)

Answer: There are 254 African animals in the zoo.
