Question

I need your assistance in solving this problem using only matrix notation. I'm facing difficulties in finding the solution without employing any other methods. Can you please provide a detailed explanation, step-by-step, using matrix notation exclusively?

this has to be done in the matrix way

Furthermore, I have attached both of the questions and answer. Could you demonstrate the matrix approach leading to the solution?
