Mathematics
1 answer:
FromTheMoon [43]2 years ago
6 0

Answer:

E started with 26 books, sold 13 books, bought 17 more books, and ended with 30 books

Step-by-step explanation:

E has _ books: x

E Sells 1/2 of that _ books: x/2

E buys 17 books and now had 30: (x/2) + 17 = 30

30 - 17 = 13

13 x 2 = 26

x/2 = 26

13 + 17 = 30       <-- checking work

My guess is that x = 13

You didn't clarify what exactly you are looking for but I hope this helps clarify some steps of the problem anyway!
