Find all the variables:

. . .\(\displaystyle \left(\begin{matrix}a&b&c \\ p&q&r \\ x&y&z \end{matrix}\right)\,\)\(\displaystyle \left(\begin{matrix}1\\1\\1\end{matrix}\right) \,\)\(\displaystyle =\, \left(\begin{matrix}6\\27\\9\end{matrix}\right)\)

. . .\(\displaystyle \left(\begin{matrix}a&b&c \\ p&q&r \\ x&y&z \end{matrix}\right)^T\,\)\(\displaystyle \left(\begin{matrix}1\\1\\1\end{matrix}\right) \,\)\(\displaystyle =\, \left(\begin{matrix}15\\15\\12\end{matrix}\right)\)

thanks!
