Could you please review the figures in the attached screenshot and confirm that I chose the correct answer, and if not, explain what I did wrong?

Figure 10 The matrix is the final matrix form for a system of two linear equations in variables x, and x2. Write the Solution of the system. 0 1 3 O A. X1 =5 X2 = 3 OB. x1 = -5 X2 = - 3 O C. x1 =5 *2 = t for any real number t OD. X1 = 3 X2 = 5 Figure 11 Find B - A. 39 - 54 B- A= 1 10 Figure 12 Perform the addition, if possible. Is the addition possible? Yes O No Complete the matrix on the right side of the equation shown below. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O B. The matrix does not exist
