10th board math question​

Answer 1

$\begin{document}\[\ x=\begin{vmatrix}-1 & -5 \\ -1 & -1 \\\hdotsfor{2} \\2 & -5 \\1 & -1 \\ \end{vmatrix}$

$\begin{document}\[\ y=\begin{vmatrix}2 & -1 \\ 1 & -1 \\\hdotsfor{2} \\2 & -5 \\1 & -1 \\ \end{vmatrix}$

To find the value of $x$ cross-multiply the determinants:

$x=\frac{-4}{3}$

To find the value of $y$ cross-multiply the determinants:

$y=\frac{-1}{3}$

Dividing both the fractions $x=-1.3$ and $y=-0.3$

Final Answer: Thus, our solutions are $-1.3, -0.3$
