Sure, I can help you with that. Here are the equations for each situation:
* High School A:

* High School B:

To determine after how many years, $t$, the number of students in both high schools would be the same, we can set the two equations equal to each other and solve for $t$. This gives us the equation:

Solving for $t$, we get:


Therefore, after 15 years, the number of students in both high schools would be the same.
