I am thinking of whole numbers. when I add them, their sum is 123. When I subtract the three lesser number from greater number, their difference is 45?
what are my numbers?

i am having trouble going step by step with this.
i added 61+62=123. i think this is wrong
please help me
thanx

  • math - ,

    I think you have a typo

    If by "When I subtract the three lesser number from greater number" you meant
    "When I subtract the lesser number from greater number" then the question is easy

    x + y = 123
    x - y = 45
    add them
    2x = 168
    x = 84
    sub that back in the first equation,
    y = 39

    the two numbers are 84 and 39

    check: 84+39 = 123
    84-39 = 45
    Yeah!
