I'm pretty sure that your answer is the Distributive Property, if I were you, I'd check your notes if you have notes or anything, and THEN, search it up. Just to make sure. I'm not always a hundred percent sure of my answer, but, I *THINK* it's the distributive property.
Both terms (1/3b and -1/3) contain the term 1/3. Factoring this out, we get:
1/3(b - 1)
