A small town has two local high schools. High School A currently has 900 students and is projected to grow by 40 students each year. High School B currently has 750 students and is projected to grow by 90 students each year. Let AA represent the number of students in High School A in tt years, and let BB represent the number of students in High School B after tt years. Write an equation for each situation, in terms of t, t, and determine how many students would be in each high school in the year they are projected to have the same number of students.
