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.

Systems k and K are not even mentioned in part I.2. So "system k was

is a figment of your imagination in no way related to A.E. article.

 Sure, but fortunately I have not written anything like this.
 I wrote, that defintions for §1.1 remain valind in §1.3, unless the author states otherwise.

If an author defines some variable or other setting and later 'foregets' this definition, all older settings remain valid.

neither K nor k are mentions in part I.1.

 Sure, but apparently you wanted to discuss a certain equation form part 1.3 on page 3.
 That was LATER than the introduction of K and k.
 

SORRY!
This was wrong.
Me culpa!
page 3 belongs to §1.1. and not to § 1.3.
§ 1.1 had not used two different coordinate systems in relative motion. Those were intruduced in the next chapter § 1.2.
(Sorry, but I make errors, too.)
In § 1.1. we have a different setting:
assumed is a single coordinate system, where Newton's equations are valid and an euclidan space, in which that coordinate system is stationary.
This setting is slightly different to the ones in the subsequent chapters.
In fact Einstein assumed here some forcefree 'flat' Euclidean space, in which one single coordinate system would be considered.
This setting is more or less motionless, hence different to the setting in the following chapters.
I personally had sorted the mentioned variables in a certain way, which was actually different than Einstein's.
For me such a single coordinate system in a forcefree euclidean space would allow only one single time measure, which is valid troughout this entire coordinate system.
Clocks could not be synchronised by light signals, however, because light needs time to travel.
To maintain the same time measure throughout that coordinate system, each remote clock needs to measure the transit delay and add that to a received timing signal, which would be sent out by kind of master clock in the center of the coordinate system.
But this was NOT, what Einstein had in mind.
Instead Einstein wanted to ignore the delay and turn the remote clocks to the received content of the timing signal (without compensation of the delay).
