The Attempt at a Solution

This assignment was given with about 20 different basic MATLAB questions and this is really the only one that I cannot get. I really don't even know where to start. I tried the online help copy and pasting different types of functions such as linsolve and solve Y but I just cannot get it to work. I also need help multiplying in matrix form. Can anyone please explain to me how to go about this. Thanks

Maybe this will help. It describes the steps needed to let MATLAB solve it.
