Question

If zeina has seven times as many books as ali if zeina gave ali 15 books they would eash have the same number of books how many books did each have

Answer 1

Zeina had 35 books and Ali had 5 books

Explanation:

Equations

We know Zeina has seven times as many books as Ali. If we call

x = Number of books Ali has

Then Zeina has

7x = Number of books Zeina has

We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:

x + 15 = 7x - 15

Adding 15:

x + 15 +15 = 7x

Subtracting x:

15 +15 = 7x - x

Operating:

30 = 6x

Dividing by 6:

x = 30 / 6

x =5

7x = 35

Thus Zeina had 35 books and Ali had 5 books
