F3 LIBOR

Hi
Can you please help with this example from your study notes as I am struggling to understand the solution.

Note sure how they got some interest rates calculation

Company X can borrow at a fixed rate of 10% or at a floating rate of LIBOR + 3%.
Company Y can borrow at a fixed rate of 12% or at a floating rate of LIBOR + 6.5%.
Company X wishes to borrow at fixed rate, whereas company Y wishes to borrow at floating rate.
Show how a swap can benefit both companies.

Regards
