step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

\begin{bmatrix}1 & 0 &  0& |5 \\ 0&  2&  0&  |8\\ 0&  0& 3&  |9\end{bmatrix}

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

\begin{bmatrix}1 &  0 & 0& |5 \\ 0&  1& 0&  |4\\0& 0& 1&  |3\end{bmatrix}
