Explanation:

Addition of matrices takes place position by position, so we need to solve the additions involving the variables. (My compulsiveness also made me check the other addiitions, but I won't type it here.)

So we need to solve the system

#4+(x-y) = 3#
#4+x=(2x+y)#

I get #x=3/2# and #y = 5/2#
