(if 2 left[ begin matrix 3&4 5&x end matrix right] + left[ begin matrix 1&y 0&1 end matrix right] = left[ begin matrix 7&0 10&5 end matrix right] ) then what is the value of (x-y)?

if\ \ 2\left[\begin{matrix}3&4\\5&x\end{matrix}\right]\ +\ \left[\begin{matrix}1&y\\0&1\end{matrix}\right]\ =\ \left[\begin{matrix}7&0\\10&5\end{matrix}\right]\
