    Tanya is 13

    Brandon is 19

    Sam is 5

    Step-by-step explanation:

    b+t+s=37

    b=t+6

    s=t-8

    plug in:

    t+6+t+t-8=37

    3t-2=37

    +2 + 2

    3t=39

    divide by 3

    t=13

    plug in

    b=13+6=19

    s=13-8=5

    t=13, b=19, s=5

    Tanya is 13

    Brandon is 19

    Sam is 5

    Tanya is 13 years old

    Brandon is 19 years old

    Sam is 5 years old

    Step-by-step explanation:

    Tanya is (x) 13

    Brandon is (x+6) (13) + 6=19

    Sam is (x-8) (13) - 8=5

    (x) + (x+6) + (x-8) = 37

    combine like terms

    3x-2=37

    add 2 to both sides

    3x-2=37

    +2 + 2

    3x=39

    divide 39 by 3

    3x=39

    :3 : 3

    x=13
