-- You've told me that there are 5 houses on a map, and
-- you've told me the address of one house.
-- You won't show me the map, but
-- you're asking me which houses are 7 miles from that one.
Can you see what's missing here ?
You haven't told me a thing about any of the other points/houses.
I don't even know if any of the others are in the same city as ' V ' is,
or even on the same planet !

So,
We need to find all points that are 7 units from point V. We can just test which ones are 7 units away by taking the absolute value of the different between their coordinates.
A. W = -7
|-7 - 3| = |-10| ≠ 7
B. X = -4
|-4 - 3| = |-7| = 7
C. Y = 4
|4 - 3| = |1| ≠ 7
D. Z = 10
|10 - 3| = |7| = 7
Points X and Z are 7 units from point V; in fact, points X and Z are the
only
points at a distance of 7 units from point V.
