13 = 2f + 5                Original Problem.
2f + 5 = 13                Flip-flopped the equation around.
2f = 8                       Subtracted 5 from each side.
f = 4                         Divided each side by 2.

Answer: f = 4
Hey there!
These are the steps involved:

1. Write out the equation.
13=2f+5

2. Turn around the equation.
2f+5=13

3. 2f+5-5=13-5
Subtract 5 from both sides.

4. [tex] \frac{2f}{2} = \frac{8}{2} [/tex]
Divide each side by 2 to simplify.

5. Once you divide, you get:
f=4

So, the final answer is 4!
