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 7 Identify the row operation that produces the resulting matrix. O A. (-1)R2 - R2 OB. (-1)R1 + R2 - R2 OC. R1 + (-1)R2 - R2 OD. R1 + (- 1)R2 - R1 Figure 8 Identify the row operation that produces the resulting matrix. O A. R1 + R2 - R1 O B. R, + R2 - R2 OC. -R1 + R2 - R2 OD. - R2+ R1 - R2 Figure 9 Solve the linear system corresponding to the following augmented matrix: 3 6 24 2 3 11 O A. (-2, -5) O B. (5, - 2) O C. (-2,5) O D. (0,0)
