Question

Last year, the school library had a total of x books. Over the summer, the library acquired another 46 books and now has a total of 1,191 books. Which equation could be used to find x, the number of books the library had last year?

Answer 1

An equation we could use to solve this is x+46=1191

Explanation:

We know that x is how many books they had. We have to add 46 to get the total of 1191, or how many books there are now. This could be used to find x by subtracting 46 from both sides.
