Thank you for the opportunity to help you with your question!

(1 + x) (1 + z) = (1 - 1/3) (1 + 5/6) 

(1 + x) (1 + z) = ((3 - 1)/3) ((6 + 5)/6) 

(1 + x) (1 + z) = (2/3) (11/6) 

(1 + x) (1 + z) = 22/18 = 11/9

Please let me know if you need any clarification. I'm always happy to answer your questions.
