Use Cramer's Rule to Solve the System of Equations $$\begin{array} { r } x - y + 2 z = 3 \\5 x + z = 3 \\x + 5 y + z = 18\end{array}$$

question 339

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { r } x - y + 2 z = 3 \\5 x + z = 3 \\x + 5 y + z = 18\end{array}$$

• A) Cramer's rule does not apply since \(D = 0 ; \varnothing\)
• B) \(\{ ( 3,3,0 ) \}\)
• C) \(\{ ( 0,3,3 ) \}\)
• D) \(\{ ( 3,0,3 ) \}\)
