Solve the System of Equations $2 x-2 y+8 z=16$ $-5 x+5 y-20 z=-40$

Multiple Choice

Solve the system of equations. If the system is inconsistent or has dependent equations, say so.
- $2 x-2 y+8 z=16$
$-5 x+5 y-20 z=-40$
$\mathrm{x}-\mathrm{y}+4 \mathrm{z}=8$

A) $\{(x, y, z) \mid x-y+4 z=8\}$ ; dependent equations
B) $\varnothing$ ; inconsistent system
C) $\{(7,3,1) \}$
D) $\{(0,0,2) \}$
