Concurrent lines? But Why?

There exist arbitrary point O and U. And set point P, Q, and R which are located on BC, AC, and AB. (which is also arbitrary)

Suppose the intersection between line PR and QU >>> Y. the intersection between line QR and PU >>> X the intersection between RU and QP >>> Z

Show that all three lines AX, BY and CZ meet in 1 point!
