After Sue  gives Tony  x of her sweets.....she has  18  - x   and he has  18 + x

 

When  she  eats  5 of her sweets after she gives Tony x sweets,  she  has  18 - x  - 5   =  (13   - x )  left    

 

And when Tony eats (1/2)  of what he has, he  has  [ 18 + x ]  / 2  left

 

So....the total  number that they have  combined =   (13 - x)  +  [ 18 + x ]  / 2
