WebA is the coefficient matrix, X the variable matrix and B the constant matrix. Multiplying (i) by A -1 we get. A − 1 A X = A − 1 B ⇒ I. X = A − 1 B ⇒ X = A − 1 B. The second method to find the solution for the system of equations is Row reduction or Gaussian Elimination. The augmented matrix for the linear equations is written. WebIf a 2×2 matrix A is invertible and is multiplied by its inverse (denoted by the symbol A−1 ), the resulting product is the Identity matrix which is denoted by I I. To illustrate this concept, see the diagram below. In fact, I can switch the order or direction of multiplication between matrices A and A −1, and I would still get the Identity matrix
