There is also no equation, which could eventually be interpreted as delay calculation.

Delay for a signal from A->B in distance x would be:

Extremely simple, isn't it?

Extremely stupid insteed x=c*t is not generally true. x/c is
not at all the delay your asking for. (AB)/c is such a delay.

So the value 'x' is a coordinate in respect to system K  with distance |x| to system K's center.

Well, yes, this was a little bad, because I had to explain it in the first place, before I could use this setting.

Systems K and k are even defined yet in paragraph 2.

It makes basically no sense to put the center of K at A and the
center of k at B. K and k are in relative motion while clock-A
and clock-B are mutually at rest. So your "setting" is setting
v to 0.

 Addendum : "the distance from A to B is x": this is wrong too.
x is the coordinate of an event in system K, it is not, in
general, the distance between origins of K and k.

'x' is a generic coordinate in system K and means a distance from the center of K to a point on the x-axis.
Since system k was placed with its center upon the x-axis and B in the center of k, the distance from A to B would actually be x.
But, of course, your critique is valid and you should not use generic variables for special purposes.
Therefore I made already the proposal to call the distance from A to B 'd'.
BTW: x was not meant as coordinate of an event, because system K and k were defined as Euclidian coordinate systems.
Such a coordinate system does not contain time in any way, hence cannot address events.
