How to Calculate value of commodity swap in the Ti BA II Plus calculator.

The question is say the forward price of oil is $22 next year and $24 year after that. The rate of interest is 5% and 5.5% respectively, hence the PV of the forward contracts is $42.515.

The Swap Value is x/1.05 + x/1.055^2 = 42.515.

How to solve for x in the calculator?

Thanks a lot for the help.
