$I = \frac{215}{26} + \frac{95}{26} i$

For $E=IZ$, where $E=35+55i$ and $Z=6+4i$, $(35+55i)=I(6+4i)$ $I = \frac{(35+55i)}{(6+4i)}$ $I = \frac{(35+55i)(6-4i)}{(6+4i)(6-4i)}$ $I = \frac{(210-140i+330i-220i^2)}{(36-16i^2)}$ $I = \frac{(210+190i+220)}{(36+16)}$ $I = \frac{(430+190i)}{52}$ $I = \frac{215}{26} + \frac{95}{26} i$
