Question:
The developers of a web site are tracking its number of adult users and teenage users. They found that the equation
64x + y = 709
models the number of teenage users over time, and the equation
161x − 2y = −118
models the number of adult users over time. In both equations, x is the number of years since 2000, and y is the number of users in thousands. During what year was the number of teenage users and adult users the same?
