question 124

Multiple Choice

Solve the system for x and y using Cramer's rule. Assume a and b are nonzero constants.
$\begin{array} { l } a ^ { 2 } x + b ^ { 2 } y = b ^ { 2 } \\a x + b y = a\end{array}$

• A) \(\left\{ \left( \frac { b } { a } , \frac { a + b } { b } \right) \right\}\)
• B) \(\left\{ \left\{ - \frac { b } { a } , \frac { a + b } { b } \right] \right\}\)
• C) \(\left\{ \left( \frac { a } { b } , \frac { a - b } { b } \right) \right\}\)
• D) \(\left\{ \left( \frac { b } { a } , \frac { a - b } { b } \right) \right\}\)
