The sum of a number and its additive inverse is equal to zero. The correct option among all the options that are given in the question is the second option or option "b". If we assume "x" to be a real number, then its additive inverse is "-x". On adding these two, we can see that the result comes to zero.
Answer:
3x + 21

So, 3*x = 3x and 3*7 = 21.
So our resulting term would be 3x+21.
