In mathematics, a system of equations, also known as a set of simultaneous equations or an equation system, is a finite set of equations for which common solutions are sought. An equation system is usually classified in the same manner as single equations, namely as one of the following:
System of linear equations System of nonlinear equations System of bilinear equations System of polynomial equations System of differential equations System of difference equations
