9776+192j<386j+2016
Add -3135 and 5151 to get 2016.
9776+192j-386j<2016
Subtract 386j from both sides.
9776-194j<2016
Combine 192j and -386j to get -194j.
-194j<2016-9776
Subtract 9776 from both sides.
-194j<-7760
Subtract 9776 from 2016 to get -7760.
j>\frac{-7760}{-194}
Divide both sides by -194. Since -194 is negative, the inequality direction is changed.
j>40
Divide -7760 by -194 to get 40.
