The figure for Exercises 29–32 shows the intersections of three one-way streets. To keep traffic moving, the number of cars per minute entering an intersection must equal the number exiting that intersection. For intersection I₁, x + 10 cars enter and y + 14 cars exit per minute. Thus, x + 10 = y + 14.

Write an equation for intersection I₂ that keeps traffic moving.
