Answer 1

The given system of equation is

x + 2y + 0z = 3

- x + y + z = 2

0x + y - 2z = - 3

The augumented matrix is formed by using the coefficient of the variables. The required matrix is shown below

`\begin{bmatrix}{1} & {2} & {0} & {3} \\ {-1} & {1} & {1} & {2} \\ {0} & {1} & {-2} & {-3} \\ {} & {} & {} & {}\end{bmatrix}`

The correct option is the second one
