Solve the System of Equations $x-y+8 z=-107$ $x+2 y=21$ $2 \mathrm{x}+\mathrm{y}+8 \mathrm{z}=-80$

Multiple Choice

Solve the system of equations. If the system is inconsistent or has dependent equations, say so.
- $x-y+8 z=-107$
$x+2 y=21$
$2 \mathrm{x}+\mathrm{y}+8 \mathrm{z}=-80$

A) $\varnothing$ ; inconsistent system
B) $\{(5,8,0) \}$
C) $\{(x, y, z) \mid 2 x+y+8 z=-80\}$ ; dependent equations
D) $\{(5,8,-13) \}$
