    Lets say we have x and y.

    Its given that y is 7 less than 3x.

    So y=3x-7

    Therefore 3x-7+x=61

    4x=68

    x=17

    61-17 = 44

    17 and 44 are your answers.

    Let x=the larger number, and let y=the smaller number. From the information given, we can get:

    x+y=61

    x+7=3y

    Subtracting the first equation from the second one, we get:

    7-y=3y-61

    -4y=-68

    y=17

    Substituting y into the first equation, we get:

    x+y=61

    x+17=61

    x=44

    Therefore, the larger number is 44 and the smaller number is 17.
