(1) vk > 0
V and K can be either positive or negative, ranging from 1 to infinity on both side of number line.
(insufficient)
(2) v - k = 6
There are many possible combination with the given equation to determine one possible answer.

Combining both : let v and k are positive integers
7-1 = 6, 8-2 = 6, ......... there are many possible combinations as the case with negative integers.
