(Getting Matriz Inverses Using Gauss-Jordan Elimination). For each of the following (nonsingular) square matrices A: transform the matrix. (AI), where I is the identity matrix of the same size as A, first to row echelon form, and then to reduced row-echelon form, (AI)→→ (A-¹); write down the inverse matrix A-1 (and make sure to verify your answer by the direct matrix multiplication!): -2 -1 -2 (1) -3 -3. 1 -2 3 -2 1 ; (iii) 2 -2 -2 -2 -1 2 2 -2 1 77-7
