Linear System of Equations and MATRICES
A linear system of equations is a set of linear equations variables. Linear systems can be represented in matrix form as the matrix equation
Ax = B
where A is the matrix of coefficients, x is the column vector of variables, and B is the column vector of solutions.
Each equation in the system becomes a row. Each variable in the system becomes a column. The variables are dropped and the coefficients are placed into a matrix. If the right hand side is included, it's called an augmented matrix. If the right hand side isn't included, it's called a coefficient matrix.
The system of linear equations ...
x + y - z = 1
3x - 2y + z = 3
4x + y - 2z = 9
becomes the augmented matrix
Now, in order to understand how to solve matrices, you need to know some terms related to this topic:
Finally, some facts about matriz definition!!!
