There are several books on both bookshelves A and B. If you take 100 books from bookshelf B and put them on bookshelf a, the books on bookshelf a are five times more than those on bookshelf B. If you take 50 books from bookshelf A and put them on bookshelf B, the books on both bookshelves are the same. How many books are there on each bookshelf, Linear equation of one variable

Let a have the original x, which means B has [(x-50) - 50]
So x + 100 = 6 * [(x-50) - 50-100]
So x = 260
So there are 260 copies for a and 160 copies for B
Upstairs do not pay attention to the title, is "more than five times", not "is five times."
