WebUsing matrix multiplication, we may define a system of equations with the same number of equations as variables as AX = B A X = B. To solve a system of linear equations using an inverse matrix, let A A be the coefficient matrix, let X X be the variable matrix, and let B B be the constant matrix. Thus, we want to solve a system AX =B A X = B. WebInversion works the same way for matrices. If you multiply a matrix (such as A) and its inverse (in this case, A −1), you get the identity matrix I, which is the matrix analog of the number 1.And the point of the identity matrix is that IX = X for any matrix X (meaning "any matrix of the correct size", of course)..
