    If we say:

    x = the smaller numbers we want to find

    y = the larger number we want to find

    Then, we can formulate two equations using the information given:

    x + y = 68 [1]

    y - 4x = 3 [2]

    Now, we can solve simultaneously:

    Rearrange [1] & [2] in terms of y:

    y = 68 - x [1]

    y = 4x + 3 [2]

    Now equate them and solve for x:

    68 - x = 4x + 3

    5x + 3 = 68

    5x = 65

    x = 13

    Sub x-value into either [1] or [2]:

    y = 68 - (13)

    y = 55
