WebApr 13, 2024 · A 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.
