Solve the System $$\left\{ \begin{array} { r } x + 9 y - z = 4 \\5 x + 45 y - 5 z = 20 \\3 x + 27 y - 3 z = 12\end{array} \right.$$

Multiple Choice

Solve the system. If there is no solution or if the system's equations are dependent, so state.
- $$\left\{ \begin{array} { r } x + 9 y - z = 4 \\5 x + 45 y - 5 z = 20 \\3 x + 27 y - 3 z = 12\end{array} \right.$$

A) no solution or $\not \supset$
B) $\{ ( 5,3,28 ) \}$
C) infinitely many solutions; dependent equations
D) $\{ ( 3,5,44 ) \}$
