Please explain every step!!

Two loudspeakers are placed in a room at positions x = 3 m and x = -3 m. They emit sound at a frequency of 686
Hz, with identical phase. The temperature is 20°C. If you stand at x = 3 m and y = 10 m and you walk outward parallel to the y axis (perpendicular to the line between the speakers), at how many different places will you hear perfectly destructive interference between the sound waves?

Please explain every step!!

Thanks in advance

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.500m . If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x =0.850m . A)What is the frequency of the sound? Assume vsound =340m/s. B)What is the phase difference between the speakers?
