It is important to know how a matrix and its inverse are related by the result of their product. so then, if a 2×2 matrix a is invertible and is multiplied by its inverse (denoted by the symbol ), the resulting product is the identity matrix which is denoted by . to illustrate this concept, see the diagram below. in fact, i can switch the. Watch this video to learn how to find the inverse of a matrix and why it is useful for solving systems of equations and other applications. Theorem 2.6.4. invertible matrices and solutions to a→x = →b. let a be an invertible n × n matrix, and let →b be any n × 1 column vector. then the equation a→x = →b has exactly one solution, namely. →x = a − 1→b. a corollary 3 to this theorem is: if a is not invertible, then a→x = →b does not have exactly one solution.

Matrix inverses can be used to solve certain systems of linear equations. recall that a system of linear equations can be written as a single matrix equation. ax = b. where a and b are known and x is to be determined. if a is invertible, we multiply each side of the equation on the left by a − 1 to get. We can either use that formula or simply the following steps instead of the formula to find the inverse of 2x2 matrix. the steps are explained with an example where we are going to find the inverse of a = ⎡ ⎢⎣ 1 −1 0 2⎤ ⎥⎦ [1 − 1 0 2]. step 1: find the det a just by cross multiplying the elements and subtracting.
