Determine Whether the Two Systems of Linear Equations Yield the Same

Multiple Choice

Determine whether the two systems of linear equations yield the same solutions.If so,find the solutions using matrices. $$\left\{ \begin{aligned}x - y - 6 z & = - 33 \\y + 3 z & = 18 \\z & = 4\end{aligned} \right.$$ $$\left\{ \begin{array} { r l r } x - 7 y - 3 z & = - 57 \\y - 9 z & = - 30 \\z & = 4\end{array} \right.$$

A) x = -3,y = 6,z = 4
B) The systems yield different solutions.
C) x = 3,y = 4,z = -3
D) x = 3,y = -6,z = 4
E) x = 6,y = 4,z = -3
