I am a 3 digit odd umber. my tens digit is one less than my hundreds digit but two more than my ones digit. The sum of my digits is 20. who am I?

  • math -

    let the unit digit be x
    tens digit is x+2
    hundreds digit is x+3

    x+3 + x+2 + x = 20
    3x = 15
    x = 5

    number is 875

    Let x = tens digit, the x + 1 = hundreds and x - 2 = ones

    3x - 1 = 20

    3x = 21

    x = 7

    x + 1 = ?

    x -2 = ?
