Landin · Answer 1

If x = number of 6 stamp pages and y = number of 9 stamp pages, then we can use a formula.

6x + 9y = 78 stamps

Or ... You could divide the total number of stamps (78) by 9 which would give you 8 and 6 as a remainder. Therefore, 8 pages would have 9 stamps and 1 page would have 6 stamps,
