Given such a model, the sentence "Y would be y had X been x" (formally, X = x > Y = y) is defined as the assertion: If we replace the equation currently determining X with a constant X = x, and solve the set of equations for variable Y, the solution obtained will be Y = y. This definition has been shown to be compatible with the axioms of ...
