Caiden Schaefer · Answer 1

Let us assume the number of turtles = x

Then

Number of frogs = x + 4

Number of crayfish = 2x + 3

Total number of turtles and crayfish = 54

Then we can write the equation as

x + 2x + 3 = 54

3x + 3 = 54

3x = 54 - 3

3x = 51

x = 51/3

= 17

Then

The number of frogs = x + 4

= 17 + 4

= 21

So there are 21 frogs in the pond that has been counted by Ramon.
