MCQ

If $\displaystyle \begin{vmatrix}\text{x} &\text{amp; } 1 \\ \text{y} &\text{amp; } 2 \end{vmatrix}-\displaystyle \begin{vmatrix}\text{y} &\text{amp; } 1 \\ 8&\text{amp; } 0\end{vmatrix}=\displaystyle \begin{vmatrix}2 &\text{amp; } 0 \\ \text{-x}&\text{amp; } 2\end{vmatrix}$ then the values of x and y respectively are:

A
5 and 1
✓
5 and 3
C
5 and 2
D
3 and 4

✓

Answer

Correct option: B.

5 and 3

x - y = 2
y - 8 = -x

Solving we get x = 5 and y = 3
