An augmented matrix is a tool used to depict a system of linear equations. To solve these equations, one must execute basic row operations until the matrix is transformed into a row-echelon form or reduced row-echelon form. Once this form is achieved, the solutions can be interpreted directly from the final matrix. These solutions correspond to the variables in the initial equations.
