question 341

Multiple Choice

Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { l } x + y = 6 \\3 x + 3 y = 18\end{array}$$

• A) Cramer's rule does not apply since \(D = 0 ; \varnothing\)
• B) Cramer's rule does not apply since \(D = 0 ; \{ ( 6 - y , y ) \}\)
• C) \(\{ ( 2,4 ) \}\)
• D) \(\{ ( 0,0 ) \}\)
