If Adam gives 13 stickers to Bryan, both will have the same number of stickers.
If Bryan gives 17 stickers to Adam, Adam has 5 times as many as Bryan.

1. How many stickers does Adam have?
2. How many stickers does Bryan have?
3. How many stickers do Adam and Bryan have altogether?
4. How many stickers does Adam have more than Bryan?

	Case 1		Case 2
	Adam	Bryan	Adam	Bryan
Before	3 u + 13	3 u - 13	5 u - 17	1 u + 17
Change	- 13	+ 13	+ 17	- 17
After	3 u	3 u	5 u	1 u

(a)
Total number of stickers in the end
= 5 u + 1 u
= 6 u

For scenario 1, Adam and Bryan have same number of stickers in the end.

Number of stickers that each boy has in the end
= 6 u ÷ 2
= 3 u

Number of stickers that Bryan has at first in both scenarios is the same.

3 u - 13 = 1 u + 17
3 u - 1 u = 17 + 13
2 u = 30

1 u = 30 ÷ 2 = 15

Number of stickers that Adam has
= 3 u + 13
= 3 x 15 + 13
= 45 + 13
= 58

(b)
Number of stickers that Bryan has
= 1 u + 17
= 15 + 17
= 32

(c)
Total number of stickers
= 58 + 32
= 90

(d)
Number of stickers that Adam has more than Bryan
= 58 - 32
= 26

Answer(s): (a) 58; (b) 32; (c) 90; (d) 26
