Solve the System of Equations $\mathrm{z}$
- $-2 x+4 y+7 z=8$

Solve the system of equations. If the system is dependent, express solutions in terms of the parameter $\mathrm{z}$ .
- $-2 x+4 y+7 z=8$
$7 \mathrm{x}+\mathrm{y}-6 \mathrm{z}=15$

A) $\left(\frac{26}{15}+\frac{31}{30} z, 15+7 x-6 z, z\right)$
B) $\left(\frac{26}{15}+\frac{31}{30} z, 15-7 x+6 z, z\right)$
C) $\left(\frac{26}{15}+\frac{31}{30} z, \frac{43}{15}-\frac{37}{30} z, z\right)$
D) $(-52-31 z,-86-52 z, z)$
