Step-by-step explanation:
because 5 is smaller then 18
(x-9)(x+7)=0
x-9=0 or x+7=0
x=9 or x=-7

You are right: the graph does not represent a proportion, because it does not go thru the origin.
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.
