MatLab help for a lost and confused student

Hello!

I'm a student in the beginning of computational linear algebra who's being kinda tossed into the deep end MatLab wise, without much instruction in how to do things, I've been given the following question that I can't figure out on my own how to do in this program.

I figured it'd be easier to include the work so I can ask how to do things, I don't necessarily want the work done for me but I DO wish to learn how to do it one way or another.

Thank you for any help you can provide!

1. Make matrix A with coefficients of the equaitions.
2. Make column matrix b with the RHS values.
3. You have equation Ax = b . Where x is unknowns.
4. Use x = A\b.

Also you can use symbolic tool box. Have a look on function solve.
