Finding Values Of Pronumerals So Matrices A and B Are Equal?
A=[2 2 -5]
....[0 1 3]

B=[x 2 -5]
....[0 1 y]

I need the answers + help on how to do it, Thanks.

As A=B
so
$
\left[\begin{matrix}2 & 2 & -5\\ 0 & 1 & 3\end{matrix}\right]=\left[\begin{matrix}x & 2 & -5\\ 0 & 1 & y\end{matrix}\right]
$

now by equating corresponding elements of of these matrices, we have
x=2
y=3(Rofl)
