I can't understand the solution and what is the variable "X" !

If you look carefully at the diagrams, the meaning of the variable "x" should be apparent. It's the <blank> along the beam from point A.

 

[Amr719]

Yes , but it is considered part of the force in the " ∑Fy " . That's what I cannot understand

One of the loads on the beam is the distributed load of 3 kips/ft, applied between points A and C.

Do you understand how a distance might be considered essential in calculating the amount of force created from a distributed load?

 

[Amr719]

No

 

[SteamKing]

No

What don't you understand about distributed loads? You know, loads spread out over a certain distance along a beam, say.
