On what ground were those abbreviations such as Dx, Fx, Hx, Sx, Tx created?

We commonly use abbreviations such as Dx for diagnosis, Fx for fracture, Hx for history, Sx for symptoms, Tx for treatment or transplant and so forth. It is quite convenient to use those abbreviations in writing a medical chart.
What I really don't understand is the reason why were those abbreviations such as Dx, Fx, Hx, Sx, Tx created by using "x"? I mean why an alphabet such as "D" followed by "x" means an abbreviation for diagnosis. Why does "x" mean an abbreviation? I can imagine that perhaps "x" means something special. But why should it be "x", not "y"?
Do you agree that this "x" might be somewhat related to the old symbol "Rx" referring to prescription?
I would appreciate it if you would provide me with some more information on my question.
