Multiple Choice

Solve the system of equations. If the system is inconsistent or has dependent equations, say so.
- $3 x-9 y+8 z=-30$
$-12 x+36 y-32 z=120$
$15 x-45 y+40 z=-150$

A) $\{(x, y, z) \mid 3 x-9 y+8 z=-30\}$ ; dependent equations
B) $\{(-8,-2,-3) \}$
C) $\varnothing$ ; inconsistent system
D) $\{(8,2,3) \}$
