Tia is 41 years old and her daughter is 5 years old.
After x years, her daughter age will be half her age. What is the value of x
~~~~~~~~~~~~~~~
Write equation as you red the problem
41 + x = 2*(5+x).
Now simplify and find x
41 + x = 10 + 2x
41 - 10 = 2x - x
31 = x
ANSWER. It will happen in 31 years.
Solved and explained.
--------------
Notice that the daughter was born when the mother was 41-5 = 36 years old.
So it is clear without calculations that the next event will happen when they will be 36 and 72 years old,
respectively, which will happen 36 - 5 = 31 years from now.
