Answer 1

8 books were in each box

Explanation:

According to the Question,

Assume X is the Number of Books In Each Box.

• We have, 4 boxes With the Same Number of Books In each Box,Thus Total Book in all box is 4X.

• And, 3 books Ryan Already Put In Shelves.

• Now, Total Number Of Book After Cleaning is 35 Books.

Algebraic Expression,

4X + 3 = 35

4X = 35 - 3

4X = 32 ⇔ X=8 books in Each Box.
