Fill in the blanks in numbers, units or unit equations.
Adam and Bryan have some stickers.
When Adam gives 35 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.
- Number of stickers that Adam has in the end = _____
- Number of stickers that Adam has at first = _____
- Number of stickers that Bryan has at first = _____
- If Adam has 80 stickers more than Bryan at first, find 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 + 35
(c)
Number of stickers that Bryan has at first = 1 u - 35
(d)
If the number of stickers that Adam has at first is 80 more than Bryan,
when we add 80 stickers to what Bryan has at first,
the number of stickers that both of them have at first will be the same.
6 u + 35 = 1 u - 35 + 80
6 u + 35 = 1 u + 45
6 u - 1 u = 45 - 35
5 u = 10
1 u = 10 ÷ 5 = 2
Answer(s):(a) 6 u; (b) 6 u + 35; (c) 1 u - 35; (d) 2
