Fill in the blanks in numbers, units or unit equations.
Adam and Bryan have some stickers.
When Adam gives 10 to Bryan,
the number of stickers he has left is 6 times as many as that of Bryan's.
Let the number of stickers that Bryan has in the end be 1 u.

1. Number of stickers that Adam has in the end = _____
2. Number of stickers that Adam has at first = _____
3. Number of stickers that Bryan has at first = _____
4. If Adam has 85 stickers more than Bryan at first, find 1 u.

	Adam	Bryan
Before	6 u + 10	1 u - 10
Change	- 10	+ 10
After	6 u	1 u

(a)
Change X times into units.

Number of stickers that Adam has in the end = 6 u

(b)
Number of stickers that Adam has at first = 6 u + 10

(c)
Number of stickers that Bryan has at first = 1 u - 10

(d)
If the number of stickers that Adam has at first is 85 more than Bryan,
when we add 85 stickers to what Bryan has at first,
the number of stickers that both of them have at first will be the same.

6 u + 10 = 1 u - 10 + 85
6 u + 10 = 1 u + 75
6 u - 1 u = 75 - 10
5 u = 65

1 u = 65 ÷ 5 = 13

Answer(s):(a) 6 u; (b) 6 u + 10; (c) 1 u - 10; (d) 13
