For which numbers \(x\) and \(y\) is the following equality true?
\[
\left (\array{
2& 3\cr
1 & -5 \cr
} \right )
\cdot
\left (\array{
x\cr
y \cr
} \right )
=
\left (\array{
1.5& x \cr
y & 5 \cr
} \right )
\cdot
\left (\array{
-2\cr
-1 \cr
} \right )
\]
\(x=-2\), \(y=1\)
\(x=2\), \(y=1\)
\(x=-5\), \(y=4\)
\(x=-2\), \(y=-1\)
