Mylene is 20 years older than her daughter Hazel.
In 10 years time she will be twice as older as her daughter. How older are Mylene and Hazel?
~~~~~~~~~~~~~~
If H is x years old, then, according to the condition, M is (x+20) years old.
In 10 years
(x+20) + 10 = 2*(x + 10).
Simplify and find x
x + 30 = 2x + 20
30 - 20 = 2x - x
10 = x
ANSWER. H is 10 years old. M is 10+20 = 30 years old.
CHECK. In 10 years, H will be 20 years old; M will be 40 years old.
In 10 years, M will be twice the age of H. ! Correct !

"twice as older" makes no sense.
============
Assuming you meant twice as old:
--------------
The age difference is constant at 20 years.
---> when they're 20 & 40.
