160, therefore a number + 3/8 has to = 160, not 170

Total number of pages in the book, we'll call that n. n=(3/8)n+53+117=...? Algebraically manipulate the function.

Alright, so let's start with n=(3/8)n+53+117. n is the total number of pages. We read 3/8 of n, so (3/8)n. Then we read 53 more pages. Then we still have 117 pages more to read. A total of n. Yes? Subtract (3/8)n from both sides. (5/8)n=53+117. Add the right side. 170. Divide by 5. 34. Multiply by 8. You get n=...?
