WebRepresenting a linear system with matrices. A system of equations can be represented by an augmented matrix. In an augmented matrix, each row represents one equation in the system and each column represents a variable or the constant terms. In this way, we can see that augmented matrices are a shorthand way of writing systems of equations. Web2.
