What is the coefficient of the x-term in the polynomial below?

  1. 7 - 2/3

  2. 21/3

  3. 19/3

  4. 8/3

The correct answer is: 21/3

The expression written in simplest form means that it cannot be further reduced or simplified. In the given options, A, C, and D can still be simplified because their fractions can be further reduced. A becomes (7/3) - (2/3) = (5/3), C becomes (19/3) = (18/3) + (1/3) = (6/3) + (1/3) = (7/3), and D becomes (8/3) = (6/3) + (2/3) = (2) + (2/3). Therefore, the only option that is already in its simplest form is B, (21/3) = (7/3), making it the correct answer.
