If Lingling had $x$storybooks, she would have had $7$comic books. Now, she wanted to make the number of comic books 3 times the number of storybooks, which meant that she wanted to have 24 times 3 = 72 comic books. Since the number of storybooks remained the same, Lingling still needed $72 - x$storybooks. To make a comic book three times the number of story books, the number of comic books should be three times the number of story books, which is $24 = 3,7 = 21 comic books. Therefore, Ling Ling now has $72 - x = 21 - 7 = 14$storybooks, where $x$is the number of original storybooks.
