Solve the System $$\begin{aligned}- 6 x - 3 y + 7 z & = - 7 \\- x + 2 y - 7 z & = - 10 \\- 3 x + 2 y - 8 z & = - 16\end{aligned}$$

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.
