If the system of equations \( p_1x + q_1y = r_1 \) and \( p_2x + q_2y = r_2 \), what is the value of y?
A) \( \frac{\begin{vmatrix} p_1 & r_1 \\ p_2 & r_2 \end{vmatrix}}{\begin{vmatrix} p_1 & q_1 \\ p_2 & q_2 \end{vmatrix}} \) B) \( \frac{\begin{vmatrix} p_1 & q_1 \\ p_2 & q_2 \end{vmatrix}}{\begin{vmatrix} r_1 & q_1 \\ r_2 & q_2 \end{vmatrix}} \)
C) \( \frac{\begin{vmatrix} r_1 & q_1 \\ r_2 & q_2 \end{vmatrix}}{\begin{vmatrix} p_1 & q_1 \\ p_2 & q_2 \end{vmatrix}} \) D) \( \frac{\begin{vmatrix} r_1 & p_1 \\ r_2 & p_2 \end{vmatrix}}{\begin{vmatrix} p_1 & q_1 \\ p_2 & q_2 \end{vmatrix}} \)
