    twice the difference between x and 28 is 3 times a number

    The difference between x and 28:
    x - 28

    Twice the difference means we multiply x - 28 by 2:
    2(x - 28)

    The phrase a number means an arbitrary variable, let's call it x
    x

    3 times a number:
    3x

    The word is means equal to, so we set 2(x - 28) equal to 3x:
    2(x - 28) = 3x
