Solve the System $$\begin{array} { l } - 2 x - 5 y + 6 z = 11 \\- x - 2 y - 7 z = - 25 \\7 x + 5 y - 7 z = 16\end{array}$$

Multiple Choice

Solve the system. If a system has one unique solution, write the solution set. Otherwise, determine the number of solutions to the system, and determine whether the system is inconsistent, or the equations are dependent.
- $$\begin{array} { l } - 2 x - 5 y + 6 z = 11 \\- x - 2 y - 7 z = - 25 \\7 x + 5 y - 7 z = 16\end{array}$$

A) Infinitely many solutions; dependent
B) $\{ ( 6 , - 1,3 ) \}$
C) No solution; inconsistent
D) $\{ ( 25,0,0 ) \}$
