WebSep 17, 2024 · To solve the matrix equation A X = B for X, Form the augmented matrix [ A B]. Put this matrix into reduced row echelon form. It will be of the form [ I X], where X appears in the columns where B once was. These simple steps cause us to ask certain questions. First, we specify above that A should be a square matrix. What happens if A isn’t square? WebAnswer. In this example, we need to solve a matrix equation. To solve this equation, we need to multiply from the left by the inverse of the given 3 × 3 matrix on both sides of the equation. Let us begin by finding the inverse of the 3 × 3 matrix: 𝐴 = 1 − 1 − 1 1 1 − 1 1 1 0 .

WebInverse matrices, like determinants, are generally used for solving systems of mathematical equations involving several variables. The product of a matrix and its inverse is the identity matrix — the square array in which the diagonal values equal 1, and all other values equal 0. WebA must be square to be invertible, so say A is an axa matrix. If we want the inverse of A, we know that A⁻¹ satisfies AA⁻¹=I, so the multiplication is well-defined. A⁻¹ must be ax (something). We also know A⁻¹A is well-defined, so by the same logic, we know that A⁻¹ will be an axa matrix. 1 comment ( 2 votes) Upvote Downvote Flag Video transcript
