The first one is:

$\left[\begin{array}{ccc}0&7&2\\5&3&1\\4&-1&6\end{array}\right]$

The second one is:

$\left[\begin{array}{ccc}1&2&6\\8&3&-2\\0&4&5\end{array}\right]$

The third one is:

$\left[\begin{array}{ccc}3&-2&5\\4&2&0\\-1&6&1\end{array}\right]$

Step by Step:

First one:

7+0+2=9

6+1+2=9

6+-1+4=9

4+5+0=9

6+3+0=9

Second one:

6+2+1=9

6+-2+5=9

4+5+0=9

0+8+1=9

1+3+5=9

Third one:

3+-2+5=6

4+2+0=6

-1+6+1=6

5+0+1=6

3+4+-1=6

3+2+1=6

Hope this helps :)
