I need to know how many of each animal type was in a pond.

Question

Mia was studying some of the pond life in a park. In 2 hours she counted four more frogs than the number of turtles she saw. The number of crayfish she counted was three more than twice the number of turtles. She counted 75 pond animals in all. How many of each animal did she find?

Answer 1

t represents the number of turtles

t + 4 represents the number of frogs

2t + 3 represents the number of crayfish

 

t + t + 4 + 2t + 3 = 75

 

Can you solve for t and answer?
