👉 Omissible is a term used in mathematics to describe an object that can be represented by a system of linear equations with constant coefficients. These equations are called Omissive Equations, and they have many applications in engineering, physics, and other fields. An Omissible System is one where the number of unknowns (the number of variables) equals the order of the equation (the degree of the polynomial). For example, a system of two linear equations with constant coefficients has an omissible form if
