How else but by experimental observation?

Explanation:

Le Chatelier's principle clearly states that when a system at
at equilibrium is subject to an external perturbation the
equilibrium will move so as to offset the external perturbation.

I usually add the proviso that offset counteract. We speak of the initial response of an equilibrium. Under the new conditions a new equilibrium could evolve.

Anyway, the principle (as with most chemical, and physical principles) derives from experiment.
