Solve the System, If Possible, by Using Cramer's Rule $$\begin{array} { l } 6 x - 9 y + 9 z = 3 \\- 4 x + 6 y - 6 z = - 2 \\2 x - 3 y + 3 z = 2\end{array}$$

question 108

Multiple Choice

Solve the system, if possible, by using Cramer's rule. If Cramer's rule does not apply, solve the system by
using another method.
- $$\begin{array} { l } 6 x - 9 y + 9 z = 3 \\- 4 x + 6 y - 6 z = - 2 \\2 x - 3 y + 3 z = 2\end{array}$$

• B) { }
• C) \(\{ ( 1 , - 1 , - 2 ) \}\)
• D) \(\left\{ \left( 1 + \frac { 3 } { 2 } y - \frac { 3 } { 2 } z \right) \mid y \right.\) and \(z\) are any real numbers \(\}\)
