Initial Number of sweets:

Tony = 18

Sue = 18

Sue Gives tony x ;

Tony = 18 + x

Sue = 18 - x

Sue eats 5 of her sweets :

Sue = 13 - x

Tony eats half of his sweets:

(18 + x) / 2

they are simplified

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
