Solve the System of Equations $x+4 y-z=3$ $-4 x-16 y+4 z=-12$

Multiple Choice

Solve the system of equations. If the system is inconsistent or has dependent equations, say so.
- $x+4 y-z=3$
$-4 x-16 y+4 z=-12$
$3 \mathrm{x}+12 \mathrm{y}-3 \mathrm{z}=9$

A) $\{(0,2,5) \}$
B) $\{(1,1,2) \}$
C) $\varnothing ;$ inconsistent system
D) $\{(x, y, z) \mid x+4 y-z=3\}$ ; dependent equations
