Solve the System of Equations $\begin{aligned}& x-y+2 z=11 \\& -2 x+2 y-4 z=3 \\& x+4 y+z=23\end{aligned}$

Multiple Choice

Solve the system of equations. If the system is inconsistent or has dependent equations, say so.
- $\begin{aligned}& x-y+2 z=11 \\& -2 x+2 y-4 z=3 \\& x+4 y+z=23\end{aligned}$

A) $\{(x, y, z) \mid x-y+2 z=11\}$ ; dependent equations
B) $\{(0,5,3) \}$
C) $\{(3,0,5) \}$
D) $\varnothing$ ; inconsistent system
