    Step-by-step explanation:

    If W is the present age of the woman and D is the present age of the daughter, then:

    W = 4D

    W + 5 = 3 (D + 5)

    Substituting the first equation into the second:

    4D + 5 = 3 (D + 5)

    4D + 5 = 3D + 15

    D = 10

    The daughter is 10 years old.
