Use Cramer's Rule to Solve the System of Equations $$\begin{array} { l } 2 x + 8 y + 4 z = - 16 \\x + 4 y + 2 z = 8 \\x + y + z = - 2\end{array}$$

question 465

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } 2 x + 8 y + 4 z = - 16 \\x + 4 y + 2 z = 8 \\x + y + z = - 2\end{array}$$

• B) \(\{ ( 4,3 , - 2 ) \}\)
• C) \(\{ ( - 2,4,3 ) \}\)
• D) Cramer's rule does not apply since \(D = 0 ; \varnothing\)
