Representative matrix and constant system of linear equations Ax = b, where X= [X1 X2 X3]T 5 7 60 4 -2 3 1 8 2 11 b = 22 55 A = Determine which of the following statements is true about X or about elementary row operations (OBE)? a. x1 =2, x2 = 9, X3=1 b. The values of the 2 components of X are x1 = 1, X3 = 3 c. The A31 element can be removed by multiplying the first row by negative two and then adding it to the third row d. Elements of A21 can be removed by multiplying the first row by a negative half and then adding it to the second row e.
