In essence, the idea is that a system of equations can be represented using matrices. The system of three equations above could be represented as follows: To see this, simply use the definition of matrix multiplication to yield. and by the definition of matrix equality, we simply find that this holds if the original three equations are satisfied.

As a first step in developing a systematic approach to solving a system of linear equations the following general principles are to be used: 1. Whenever possible, equivalent systems of equations will be retained. Hence, if the initial system has 4 equations, then, in subsequent equivalent systems that we write down, 4 equations should be ...

Solving Systems of Linear Equations in Three Variables
A system of equations in three variables is any system that essentially contains three unknown quantities. The variables x, y, and z are usually used to represent these unknown values. Needless to say, a system of linear equations in three variables is a system that meets both conditions listed above.
