Need help with matrices :/
6. Given that the matrix is skew-symmetric, find the value of x+y+z
7. Find the value of x which makes the matrix ![A=\left[\begin{array}{ccc}-1&5x-3\\-43&-8\end{array}\right]](/tpl/images/2310/3840/ca81d.png)
symmetric
8. If ![A=\left[\begin{array}{ccc}-6&-2y&-y-3x\\z+5&-9&z-6\\-9-2x&-11&-4\end{array}\right]](/tpl/images/2310/3840/5201c.png)
is a symmetric matrix, what are the values of x, y, and z?
![B=\left[\begin{array}{ccc}0&-2x&-63\\z+14&0&3z\\-3y+6x&-12&0\end{array}\right]](/tpl/images/2310/3840/ff187.png)
