Use Cramer's Rule to Solve the System of Equations $$\begin{array} { l } 8 x - 9 y + 4 z = 0 \\- 4 x + 5 y + 5 z = 60 \\3 x - 7 y - 8 z = - 105\end{array}$$

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } 8 x - 9 y + 4 z = 0 \\- 4 x + 5 y + 5 z = 60 \\3 x - 7 y - 8 z = - 105\end{array}$$
