WebAnswer. To calculate the determinant of a 3 × 3 matrix, recall that we can use the cofactor expansion along any row using the formula d e t ( 𝐴) = 𝑎 𝐶 + 𝑎 𝐶 + 𝑎 𝐶, where 𝑖 = 1, 2, or 3, and along any column. Although any choice of row or column will give us the same value for the determinant, it is always easier to ... WebA linear system in upper triangular form can easily be solved using back substitution. The augmented coefficient matrix and Gaussian elimination can be used to streamline the process of solving linear systems. To solve a system using matrices and Gaussian elimination, first use the coefficients to create an augmented matrix.
