x – 5y – z = 1
y – z = 2
x – 5z =1
1. Write the system above in Ax=b form using matrices and find the inverse of coefficient matrix (A-1

2. Then, solve the linear system using A^-1 matrix you obtained in (1)
3. For the first two row operations you used to find A-1 in (1), write corresponding elementary matrices
and their inverses (E1 , E2 , E1^-1, E2^-1).

x- 5y – z = 1
y -z=2
- 5z =1
