What is X on an ice table ?

X is just a variable used to find the value you are looking for. I would set X as whatever concentration the question is asking you to find.

X represents the change in concentration, it can either be positive or negative whether it is increasing or decreasing.

X is the variable you use to represent the unknown concentration of something. -X and +X therefore then represent the change in concentration of a reactant.

The x is just a variable that represents the change in concentration, which we are trying to solve for.

X is the change in concentration from reactants to products, thus, the reactant's end concentration would be its initial-change(which is x), the products, on the other hand, are just x since they are equal to the change in concentration from the reactant.
