Document Description

Learn about systems of equations concept. A "system" of equations is a set or group of equations. Linear equations are easy than nonlinear equations, and the simplest linear system is one with two equations and two variables. System of equations is a collection of two or additional equations with a same set of unknowns. In solving a system of equations, we need to find values for every of the unknowns that will declare every equation in the system. The system of equation can be linear or nonlinear. The problem can be spoken in sequence of actions form or the problem can be expressed in algebraic form. Types of Systems of Equations Elimination : Elimination technique is considered as one of the algebraic method for solving systems. In elimination method an operation on 1 equation is performed so that cancelling one variable and finding the other variable.
