Consider the system of equations written as a matrix equation, which of the following is correct? Select one: O a. x2 + x2 - xy = 4 X1 - 2x2 + 3x3 = -6 2x1 + 3x2 + x3 = 7 -0-8 AX=B O b. None of options. 1 O c. x + x2 - xy = 4 X; - 2x2 + 3x3 = -6 2x: + 3x2 + x3 = 7 - 1 2 1 --23 3 AX=B 1 - -1 4 3 O d. xy + xy - x3 = 4 X; - 2x2 + 3x3 = -6 2xy + 3x2 + x3 = 7 -6 2 3 1
