    The no. of hard cover non-fiction, x = 20 books

    Solution:

    Total no. of books owned by Thabo, t = 140 books

    Let the no. of hard cover non-fiction books be x

    Then the no. of paper back non-fiction books, y = x + 20

    According to the question the no. of paper back fiction books = 2 (x + 20)

    Now,

    x + y + 2 (x + 20) = 140

    x + x + 20 + 2x + 40) = 140

    4x = 80

    x = 20
