Answer:

I think it would be A

Step-by-step explanation:

I think this because of the books are x and the magazines are y. They also said there are 3 more magazines, than books so that would be subtraction and not adding or anything else.

First one because book is x magazine is y
X+y=47

Magazine is 3 morethan books
Y=x+3
or,y-x=3

That means it’s just interexchanged
