Tkeumiz1Er VOS Consider a non-singular (invertible) matrix A with three rows and three columns. By sequentially performing (respecting the order in which they are stated) the elementary operations on rows in matrix A described below, the identity matrix is reached: • Add in row 2 the result of -4 times row 1: -4F1 F2 → F2. • Swap.row 2 with row 3: F2>F3 • Add in row 1 the result of 5 times row 3:5F3 +F1- F1 With certainty, A-1 corresponds to the matrix: -19 5 a) 0. 0 1 -4 1 : b) -4 0-19 1 c) 0. 1 4 1 -20 1 d) -4 -20 1. 1.
