Simultaneous equations

In mathematics, a set of simultaneous equations, also known as a system of equations , 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 bilinear equations,
  • System of polynomial equations,
  • System of ordinary differential equations,
  • System of partial differential equations, or a
  • System of difference equations

In econometrics:

  • Simultaneous equations model, a statistical model in the form of simultaneous linear equations
