"15 S" is closer to the equator than "40 N" is ... actually regardless of the 'S' or 'N'.
128 is closer to 125 than 120

A city located at 120 degrees E is next to the east of the Prime Meridian but not necessarily next to the Equator. The Equator is at 0 degrees latitude, so the city's latitude would determine if it is close to the Equator.
The coordinates 30 S and 120 E correspond to Australia.
Using the spherical coordinate system, they would be (6378 km, 40, -120).
The geographic coordinates of 0°N, 120°E correspond to the location in the country of Indonesia.
Those are invalid coordinates. You can't have more than 90 degrees north.
If you mean: 8x2-64x+120 = 0 then x = 3 or x = 5
