Two long parallel transmission lines $37\mathrm{.}0$ cmcm apart carry $21\mathrm{.}0$ AA and $74\mathrm{.}5$ AA currents. Find all locations where the net magnetic field of the two wires is zero if these currents are in opposite directions.

Please, enter your answer as two distances, the first distance from the wire carrying $21\mathrm{.}0$ AA $,$ and the second distance from the wire carrying $74\mathrm{.}5$ AA $.$ Separate the values with a comma.
