(a)
Charlie has 30 stickers more than Bryan.
Adam has 20 stickers less than Charlie.
Let the number of stickers that Bryan has be 1 u.
Charlie has 30 stickers more than Bryan.
Number of stickers that Charlie has = 1 u + 30

Adam has 20 stickers less than Charlie.
Number of stickers that Adam has
= 1 u + 30 - 20
= 1 u + 10

= 1 u + 1 u + 1 u + 30 + 10
= 3 u + 40
