WebIn mathematics and particularly in algebra, a system of equations (either linear or nonlinear) is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity. WebAn inconsistent set of propositions is a set of propositions s. (such that) its members cannot be true together. Explication of the phrase “cannot be true together”: there is no possible evaluation of the simple structural elements of the propositions in question that renders all propositions true.
