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 on the right.

Effect of elementary row operations on determinant? 0. Determinants and row operations. 1.For a 4x4 determinant I would probably use the method of minors: the 3x3 subdeterminants have a convenient(ish) mnemonic as a sum of products of diagonals and broken diagonals, with all the diagonals in one direction positive and all the diagonals in the other direction negative; this lets you compute the determinant of e.g. the bottom-right 3x3 as 71*73*38 + 78*32*50 + …
