Determine Whether the Two Systems of Linear Equations Yield the Same

Determine whether the two systems of linear equations yield the same solutions. If so, find the solutions using matrices.
$\left\{ \begin{array} { r } x + 9 y - 2 z = 41 \\ y - 7 z = 46 \\ z = - 6 \end{array} \right.$
$\left\{ \begin{aligned} x + 4 y + 2 z & = - 3 \\ y + 5 z & = - 26 \\ z & = - 6 \end{aligned} \right.$

A) $x = - 7 , y = 4 , z = - 6$
B) $x = 7 , y = - 4 , z = - 6$
C) $x = - 4 , y = - 6 , z = - 7$
D) $x = 4 , y = - 6 , z = - 7$
E) The systems yield different solutions.
