Answer:

3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)

After the row operation replaces the second row, the augmented matrix is ...

\begin{gathered}\left[\begin{array}c-6&3&-4\\0&-3&11\end{array}\right]\end{gathered}[−603−3−411]

Answer:


\left[\begin{array}c-6&3&-4\\0&-3&11\end{array}\right]

Explanation:

The designated sum can replace either row. Consult your curriculum materials for the intent.

Here, we'll replace row 2 with the sum.

3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)

After the row operation replaces the second row, the augmented matrix is ...


\left[\begin{array}cc-6&3&-4\\0&-3&11\end{array}\right]
