question 284

Multiple Choice

Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- $$\begin{array} { c } x + y = 5 \\5 x + 5 y = 25\end{array}$$

• A) Cramer's rule does not apply since \(D = 0 ; \varnothing\)
• B) Cramer's rule does not apply since \(D = 0 ; \{ ( 5 - y , y ) \}\)
• C) \(\{ ( 0,0 ) \}\)
• D) \(\{ ( 6 , - 1 ) \}\)
