Solving for k & P0: 5 Decimal Places of Accuracy

[Destrio]

From the facts that 1150 = P0exp(2 k) and 11500 = P0exp(8 k) we can solve for k and P0. Provide at least five decimal places of accuracy for k and at least two decimal places of accuracy for P0.

I've got
P0 = 1150/e^2k
and
P0 = 11500/e^8k

but when i try to solve for any variable by substituting I keep ending up cancelling out all the variables
help!

thanks

nvm i had crazy algebra

Dividing one equation by the other eliminates P0.
