HOMEWORK HELP! JUST ONE PROBLEM!!!!!!?

1

the thousands digit of a 4-digit number is 4 greater than the hundreds digit. The tens digit is 2 times the thousands digit. The ones digit is one-half the thousands digit. What is the number?

PLEASE help. I honestly wouldn't ask if I wasn't so hopelessly stuck! I have to show my work so if you could please show how you got your answer that'd be great. I know it's hard and sorta complicated but if you try thank you that's all I ask :)

    "the thousands digit of a 4-digit number is 4 greater than the hundreds digit."

    So could be

    40xx

    51xx

    62xx

    73xx

    84xx

    95xx

    "The tens digit is 2 times the thousands digit"

    The tens digit must be a single digit 9 or less. That means the thousands digit must be 4 or less. So from the above list that only leaves

    40xx

    Adding the tens digit we have

    408x

    "The ones digit is one-half the thousands digit."

    So we now have

    4082
