Solve Using Cramer's Rule, If Possible $$\left\{ \begin{array} { l } 4 x - 4 y - 4 z = - 20 \\- 8 x + 3 y - 3 z = - 68 \\- 7 x - 7 y - 5 z = - 117\end{array} \right.$$

Multiple Choice

Solve using Cramer's rule, if possible. If it is not possible, state whether the system is inconsistent or has infinitely many
solutions.
