यदि \( D_x = \begin{vmatrix} 4 & 2 \\ 2 & 6 \end{vmatrix} र D_y = \begin{vmatrix} 4 & 1 \\ -2 & 7 \end{vmatrix} \) भए x र y का मानहरू पत्ता लगाउनुहोस् ।
If \( D_x = \begin{vmatrix} 4 & 2 \\ 2 & 6 \end{vmatrix} and D_y = \begin{vmatrix} 4 & 1 \\ -2 & 7 \end{vmatrix} \) then find the values of x and y.
