In the exam 2021, Problem 3, Question 4, how does the solution perform the second equality (where the numerator becomes p+w)?
Thanks

Hello,
Thank you for your question.
With a bit of work, you could prove that if a/b = c/d then a/b = c/d = (a+b)/(c +d); the second equality is obtained using this fact.
