Use Cramer's Rule to Solve the System of Equations $$\begin{array} { l } x - y + z = 2 \\x + y + z = 8 \\x + y - z = 0\end{array}$$

Multiple Choice

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

A) $\{ ( 1,4,3 ) \}$
B) $\{ ( 4,1,3 ) \}$
C) Cramer's rule does not apply since $D = 0$ ; $\varnothing$
D) $\{ ( 1,3,4 ) \}$
