Question

Sue has 18 sweets

tony also has 18 sweets
sue gives tony x sweets
sue then eats 5 of her sweets
tony then eats half od his sweets
write expressions for the number of sweets sue and tony now have

Answer 1

(18 - x) - 5 = Sue

( 18 + x ) / 2 = Tony

Explanation:

Sue gives away x so that subtracts x. Then she eats 5 of hers so that subtracts 5 more. Tony gains x so that would be added. Then he eats half of his so that divides it by two.
