M8 Inverse of a 2x2 matrix Learning Lab
That is just equal to-- that's this thing right here-- 1 times 4 minus 3 times 2, which is equal to 4 minus 6, which is equal to minus 2. So the determinant is minus 2, so this is invertible. Not only is it invertible, but it's very easy to find its inverse now. We can apply this formula.

About the method. To calculate inverse matrix you need to do the following steps. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Reduce the left matrix to row echelon form using elementary row operations for the whole matrix (including the right one). As a result you will get the inverse calculated.
