$[\begin{array}{c} 2 & 0 & - 4 \\ 6 & 4 & 2 \\ 8 & 0 & 6 \end{array}] + [\begin{array}{c} - 3 - 3 & - 3 & - 9 & 0 \\ - 12 & - 6 & - 3 & - 3 \\ - 9 & - 6 & 0 & - 3 \end{array}]$

Step 1

Subtract $3$ from $- 3$ .

$[\begin{array}{c} 2 & 0 & - 4 \\ 6 & 4 & 2 \\ 8 & 0 & 6 \end{array}] + [\begin{array}{c} - 6 & - 3 & - 9 & 0 \\ - 12 & - 6 & - 3 & - 3 \\ - 9 & - 6 & 0 & - 3 \end{array}]$
