  2. Step-by-step explanation:

    Given:–

    the sum of two facing pages of an opened book is divisible by 3 , the sum is 21

    To find:–

    what are the two facing pages?

    Solution:–

    Let the facing pages of an opened book be X and X+1

    Given that

    The sum of two facing pages of an opened book =21

    => X+X+1 = 21

    => 2X+1 = 21

    => 2XX = 21-1

    => 2X = 20

    =>X = 20/2

    => X =10

    X+1 = 10+1 = 11

    Answer:–

    The two facing pages of an opened book are 10 and 11

    Check:–

    Pages are 10 and 11

    Their sum = 10+11=21 is divisible by 3
