19) Use elementary row operations to transform the augmented coefficient matrix to echelon form. Then solve the system by back substitution. a) x1 - 3x2 + 4x3 = 32 2x1 + x2 + x3 = 8 - 3x1 + 2x2 - 2x3 = - 25 b) x1 + x2 + x3 + x4 = 7 2x1 - x2 + x3 = 3 3x1 + 2x2 + x3 - x4 = 9 c) 7x1 - 7x2 + 4x3 = - 5 21x1 - 21x2 + 12x3 = - 13 14x1 - 14x2 + 8x3 = - 7 d) - x1 + x2 + x3 = - 1 - x1 + 3x2 - 7x3 = - 15 7x1 - 6x2 - 11x3 = 0
