Answer:

f = 8

Explanation:

First, let's multiply this equation out

10 = 3f - 15 + 1

Simplify:

10 = 3f - 14

Add 14 to both sides:

24 = 3f

Divide both sides by 3:

f = 8

Let's plug this in to make sure:

10 = 3(8 - 5) + 1

10 = 24 - 15 + 1

10 = 24 - 14

10 = 10

Thus, the answer is not -75, but I applaud you for trying before coming here!

I hope this helped!
