Alright, lets get started.
Friday's night game, fan are given = X
half of the fans at Fridays night fans = [tex]\frac{x}{2}[/tex]
On Saturday, there were 18 less fans than half the fans at Friday night's game
Means
Saturdays night game, fanes = [tex]\frac{x}{2} -18[/tex]
So, the expression representing the number of fans at Saturday's game will be [tex]\frac{x}{2} -18[/tex] : Answer
Hope it will help :)
