question 5

Multiple Choice

Solve using Cramerʹs rule.
- $$\begin{array} { l } 5 x _ { 1 } + 9 x _ { 2 } = - 3 \\5 x _ { 1 } + s _ { 2 } = 4\end{array}$$

• A) \(s \neq \pm 5 ; x _ { 1 } = \frac { - 3 s - 36 } { 5 ( s - 5 ) ( s + 5 ) }\) and \(x _ { 2 } = \frac { 4 s + 3 } { 5 ( s - 5 ) ( s + 5 ) }\)
• B) \(s \neq 3 ; x _ { 1 } = \frac { - 3 s + 36 } { 5 ( s - 3 ) ( s + 3 ) }\) and \(x _ { 2 } = \frac { 4 s - 3 } { ( s - 3 ) ( s + 3 ) }\)
• C) \(s \neq \pm 3 ; x _ { 1 } = \frac { - 3 s - 36 } { 5 ( s - 3 ) ( s + 3 ) }\) and \(x _ { 2 } = \frac { 4 s + 3 } { ( s - 3 ) ( s + 3 ) }\)
• D) \(s \neq \pm 9 ; x _ { 1 } = - 3 s - 36\) and \(x _ { 2 } = 4 s + 3\)
