Answer:75 pages.

Step-by-step explanation:Let the total number of pages in the book be x.

According to the question,

(3/5 of x) + (4/5 of x) – (30) = x

3x/5 + 4x/5 – 30 = x

(3x + 4x) / 5 = x + 30

7x = 5 (x + 30)

7x = 5x + 150

7x – 5x = 150

2x = 150

x = 150/2

x = 75 pagesHope it helps u !!!!!!
