Keisha read twice as many books this year as ben read. subtracting 4 from the number of books Keisha read and dividing by 2 gives the number of books Sheldon read. Sheldon read 10 books. How many books did Ben read?

  • algerbra -

    books read by Ben ----- x
    books read by Keisha --- 2x

    Sheldon ------ (2x-4)/2

    (2x-4)/2 = 10
    2x-4 = 20
    2x = 24
    x = 12

    Ben read 12 books
    Keisha --- 24

    Sheldon: (24-4)/2 = 10
