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
