b) Set up an equation using the variable you defined in (a):
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Explanation:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
We are told in the question:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.
Therefore,
3× f - 2 = 11 + 2
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Solving the above equation:
3f - 2 = 13
3f = 13 + 2
3f = 15
Divide both sides by 3
3f/3 = 15/3
f = 5
Hence, Ms. Montesinos has 5 fishes
