Answer:
A. x + 46 = 2,749
Step-by-step explanation:
The total MUST be 2,749 as it is the amount of books added and the amount of books that were present from before; therefore, the books in total is 2,749.
x remains there, for the library had already had (x) amount of books from before.
46 is added to x because 46 is the amount of books acquired, in addition to (x) amount of books.
Therefore, the answer is x + 46 = 2,749
