Kim is reading a book with 380 pages. She read 20 pages each day until she reached Part 2 of the book. Part 2 of the book is 160
pages long. She uses the equation 380−20=160 380 - 20 d = 160 to represent the number of days, d, it took her to read Part 1. How many days did it take Kim to read Part 1 of the book?
First you have multiply 6 by both 3x and 8 6*3x = 18x 6*8= 48 18x + 48 + 32 + 12x now combine like terms 18x + 12x = 30x 48 + 32 = 80 so 30x + 80 is your answer
