System of equations

In mathematics, a set of simultaneous equations, also known as a system of 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 a:


 * System of linear equations,
 * System of nonlinear equations,
 * System of bilinear equations,
 * System of polynomial equations,
 * System of differential equations, or a
 * System of difference equations
