Answer variants:

[\begin{array}{l} -4 & 9 & -1 \\ 10 & -2 & 9 \\ -7 & -9 & -9 \end{array}]

[\begin{array}{l} -5 & 8 & -1 \\ 6 & -2 & 9 \\ -7 & -9 & -9 \end{array}]

[\begin{array}{l} -5 & 9 & -4 \\ 6 & -4 & 10 \\ -11 & -9 & -9 \end{array}]

Find the Additive Inverse if \(A = \begin{bmatrix}
5 & -9 & 4\\
-6 & 4 & -10\\
11 & 9 & 9
\end{bmatrix}\)

Additive Inverse of \(A\) is
