Solve the System $$\left\{ \begin{array} { r r } x + y + z = & 2 \\x - y - 2 z = & - 10 \\3 x + 3 y + 3 z = & 6\end{array} \right.$$

Multiple Choice

Solve the system. If there is no solution or if the system's equations are dependent, so state.
- $$\left\{ \begin{array} { r r } x + y + z = & 2 \\x - y - 2 z = & - 10 \\3 x + 3 y + 3 z = & 6\end{array} \right.$$

A) infinitely many solutions; dependent equations
B) $\{ ( - 4,4,2 ) \}$
C) no solution or $\varnothing$
D) $\{ ( - 4,2,4 ) \}$
