How do we systematically calculate the molar solubility of a substance with regards to its K_sp? In other words, where does the value of "molar solubility" fit in to the equilibrium calculations?

This should build up so that I can understand how to systematically treat the common ion effect, among other equilibria, if necessary. For example, if I want to know what the molar solubility is of my salt when, if it dissolves, it will undergo hydrolysis of the anion, or complex formation, or both (so we would need to consider acid/base equilibria and K_f at the same time as K_sp), how do I set up the equilibrium expressions to solve to get my molar solubility? This would come from an understanding of how exactly to calculate "molar solubility" in relation to equilibria in general.
