Sorry, I made messed up entirely.
A. Jameston High School Enrollment: 2020 - 125n
Townsville High School Enrollment: 1075 + 80n.
B. To find out when they will have the same enrollment would be: 2020 - 125n = 1075 + 80n
Solve 2020 - 125n = 1075 + 80, to get 2020 = 1075 + 205n, solve that further.
I'm sure you know what to do from there. Sorry for the confusion.
