I am working with the formula that calculates the present value annuity factor given that interest is compounded continuously

PVIFA = [1 - e^-in]/[e^i - 1]

I am not able to solve for i or n for the reason that I am not getting the e^in cornered on the left side of the equation

After multiple tries the best I have gotten is

[e^in - 1] / [e^in {e^i-1} ] = PVIFA

Any suggestions on how to proceed for simplifying this further
