    15 years old

    Step-by-step explanation:

    x+ 10= (x-10) ^2

    x=15

    15+10= (15-10) ^2

    25= (5)^2

    15

    Step-by-step explanation:

    15-10= 5

    so 10 years ago her/ his age is 5

    15+10= 25

    so 10 years from now her/his age will be 25

    checking:

    5 squared = 25

    so true..
