WebThis is a 3 by 3 matrix. And now let's evaluate its determinant. So what we have to remember is a checkerboard pattern when we think of 3 by 3 matrices: positive, negative, positive. So first we're going to take positive 1 times 4. So we could just write plus 4 times 4, the determinant of 4 submatrix. 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.
