Summary
















1.0 – Introduction
For the simplicity, a system of linear algebraic equation can be solved numerically. Four different methods of solution will discuss in the following section.

2.0 – Matrix Inverse Method
This method is used in solving systems of linear algebraic equations. The following steps are required:
If the following equations are given and we asked to solve X,Y, and Z.
aX+bY+cZ=d (1)
eX+fY+gZ=h (2)
jX+kY+mZ=n (3)
