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?

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

Step-by-step 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.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
