    pam is 51 and jan is 48

    Step-by-step explanation:

    pam is x and jan is y

    (x + 3) + y = 99

    - 3 on both sides

    x + y = 96

    divide 96 by two

    96/2 is 48

    add 3 to 48 (pam's age)

    pam is 51 and jan is 48

    Pam is 51.

    Jan is 48.

    Step-by-step explanation:

    Pam is 3 years older than Jan so her age is x + 3 where x is Jan's age. When we add Pam's age and Jan's age, the sum equals 99.

    So x + x+3 = 99. Solve for x.

    2x+3 = 99

    2x=96

    x = 48

    So Jan is 48 years old. This means Pam is 51.
