Interpret the given matrix as a system of linear equations. Use x for the first variable, y for the second variable, and z for the third variable. $ \left[\begin{array}{ccc}4 & -6 & 8 \ -2 & \frac{6}{7} & 7\end{array}\right] $

A)
$ \left\{\begin{array}{r}4 x-6 y+8 z \ -2 x+\frac{6}{7} y+7 z\end{array}\right\} $

B)
$ \left\{\begin{aligned} 4 & =6 x+8 y \ -2 & =\frac{6}{7} x+7 y\end{aligned}\right\} $

C)
$ \left\{\begin{aligned} 4 x-6 y & =8 z \ -2 x+\frac{6}{7} y & =7 z\end{aligned}\right\} $

D)
$ \left\{\begin{aligned} 4 x-6 y & =8 \ -2 x+\frac{6}{7} y & =7\end{aligned}\right\} $
