Matrices and Systems of Equations
You can use a matrix to solve a system of equations. There are many ways to do so. One of them involves finding the augmented matrix and performing row operations on that matrix using the Gauss Elimination method and the Gauss-Jordan Elimination method. Both will be explored in this chapter among other methods.
