Urgent A-level maths help requested (duplicate posting)

My daughter has been given a chapter of an old Maths book to look at prior to her university interview. She understands all of it except this question, and has worked out the following. It's important to use the substitutions given. I'll post on the 6th form and Maths forums too. Any help would be great as the interview is tomorrow!

I'm afraid I can't help you 2Girlsmum but am replying to bump this in the hope that G55 sees it. Can't get hold of DD1 to ask... good luck!
