1. The problem statement, all variables and given/known data
|2z -1|$\geq$|z + i|

3. The attempt at a solution
The problem I have with this one is the 2z, I just need a clue on how to go about centering this one. If it were just |z - 1|; z$_{0}$ would be 1.

Hi NewtonianAlch!

2|z - 1/2| ≥ |z + i|
