On the other hand, what if you could find the inverse of A, something similar to finding the reciprocal fraction above? The inverse of A, written as "A–1" and pronounced "A inverse", would allow you to cancel off the A from the matrix equation and then solve for X.

We learn how to find the inverse of a matrix, whihc we use later to solve systems of linear equations. ... The first method is limited to finding the inverse of 2 × 2 matrices. It involves the use of the determinant of a matrix which we saw earlier. ... This method is only good for finding the inverse of a 2 × 2 matrix.

Like much mathematics, finding the inverse of a matrix is more difficult to describe than it is to actually do, so this will effectively be a worked example. ... Finding the inverse of a 3X3 matrix will be shown; and then it will be illustrated how this generates the same result as the above identity for a 2X2. With a bit...
