Fundamentals of Equilibrium Concentration Reactions

Consider mixture C, which will cause the net reaction to proceed in reverse. [Refer to image] The change in concentration, x, is positive for the reactants because they are produced and negative for the products because they are consumed. Based on a Kc value of 0.130 and the table given, what are the equilibrium concentrations of [XY], [X], and [Y] respectively?.
