Given the following system AXb, shown below. 5x3 - 3x2 21 = 1 8 x2 - 4x1 - 3x3 = 4 8 x1 - 4x2 3x3 = 5 Assuming that the unknown vector X is the transpose of X1 X2 X3 in that order If an iterative methode. Jacobi Gauss Seidelor Successive Relaxation) to be used to solve the system The action to be taken to guarantee convergence, Select the best answer: For matrix A switch column 2 with column 3, and for vector X switch row 2 with row 3. switch the rows of A and b such that row 1 switched with row 3 switch the rows of A and b such that row 2 switched with row 1. No action is needed, the matro satisfy the convergence condition
