(1 point) Suppose that: 3 -4 -5 A= and B = -2 -3 -1 5 5 -5 -5 Given the following descriptions, determine the following elementary matrices and their inverses a. The elementary matrix 191 multiplies the first row of A by 1/3. b. The elementary matrix 19% multiplies the second row of A by -2. C. The elementary matrix 15% switches the first and second rows of A. d. The elementary matrix My adds 3 times the first row of A to the second row of A. EA e. The elementary matrix 15, multiplies the second row of B by 1/3. E f. The elementary matrix 10% multiplies the third row of B by -5.e. The elementary matrix 15, multiplies the second row of B by 1/3. E, = E = f. The elementary matrix Es multiplies the third row of B by -5. = E = g. The elementary matrix 15, switches the first and third rows of B. E, 1 = E. = h. The elementary matrix E: adds 7 times the third row of B to the second row of B. = E: =(1 point) Solve for X. 5 X. 8 181x + 13 31-1 9 3 X =
