(10 pts) Solve the linear system

using the process developed in class (don't do any row swapping). In particular do the steps below (show all work):

- a)
- Compute the
*LU*factorization of*A*. Explicitly state the*L*and*U*matrices. Verify that - b)
- Solve
*Lz*=*b*for*z*. - c)
- Solve
*Ux*=*z*for*x*.
