$x=5$ and $y=5/2$

Set the corresponding positions in the two matrices equal to one another.

$4x=15+xcolor(white)(aaa)$ and $color(white)(aaa)5=2y$

$4x=15+xcolor(white)(aaaaaaaaa)5/2=(2y)/2$
$-xcolor(white)(aaaa)-x$

$(3x)/3=15/3color(white)(aaaaaaaaaaa)5/2=y$

$x=5$

How do you find the values of x and y given [(4x), (5)]=[(15+x), (2y)][(4x), (5)]=[(15+x), (2y)]?
