SOLUTION

We want to solve the question below

We can see that a matrix was subtracted from another. In Addition or subtraction of matrix, we just add or subtract the element. So

We have in the first row

[tex]\begin{gathered} -20-(-5)=x \\ -20+5=x_ \\ x=-15 \end{gathered}[/tex]

And

[tex]\begin{gathered} 16-1=y \\ 15=y \\ y=15 \end{gathered}[/tex]

Hence x = -15 and y = 15, the first option is correct
