The net electric flux through a closed surface is given by Gauss's law, which states that it is equal to the net charge enclosed divided by the permittivity of free space ($\epsilon_0$). The net charge enclosed is $+12 \mu C - 6 \mu C = 6 \mu C$. Therefore, the flux is $6 \times 10^{-6} C / (8.85 \times 10^{-12} C^2/N·m^2) = 6.8 \times 10^5 N·m^2/C$.
