Question

Sue has 18 sweets.

Tony also has 18 sweets.
Sue gives Tony x sweets.
Sue then eats 5 of her sweets.
Tony eats half of his sweets.
Write an expression for the number of sweets Sue and Tony have?

Answer 1

see below

Explanation:

18 - x - 5 = for sue

(18 + x)/2 = for tony

to put the combined total together

18 - x - 5 + (18 + x)/2

well the X's cancel out since it stays between them

18 - 5 + (18)/2

18 - 5 + 9

18 + 4

22 candies
