I need the steps for calculating the following problem on a financial calculator (BA II Plus), please. I already have the answers but I specifically need to know the steps to simplify the work using the financial calculator. Thank you!

A 6% six-year bond yields 12% and a 10% six-year bond yields 8%. Calculate the six-year spot rate. Assume annual coupon payments. (Hint: What would be your cash flows if you bought 1.2 10% bonds?)
