(a) If A is an 3 x 3 matrix and A = 03x3, then A = O3x3. (Here, O3x3 is the zero 3 x 3 matrix.) (b) If A, B, and C are 2 x 2 matrices and AB = AC, then B = C. (c) If A, B, and C are m x n matrices and A + C = B+C, then A = B.

(a) If A is an 3 x 3 matrix and A = 03x3, then A = O3x3. (Here, O3x3 is the zero 3 x 3 matrix.) (b) If A, B, and C are 2 x 2 matrices and AB = AC, then B = C. (c) If A, B, and C are m x n matrices and A + C = B+C, then A = B.

Need you guys help on this
Doesn't quite answer my question...I asked if there's a way to reason the answer WITHOUT plugging in numbers, and if not, what would be the METHOD for choosing what numbers to plug in. I didn't ask to just solve the problem. Please explain. Thank you
I can't tell what the answer is supposed to be. None of the answers are the same as the options and the answer is option -g There is no g. Can you please clear up the answer by writing it legibly.
