Answer:
Phillip is 14 years old .
Explanation:
We have:
Phillip's mother is 5 years older than twice Phillip's age.
Let Age of Phillip be 'P' years.
Age of Phillip's mother will be 2P + 5 years
Also, we have :
Phillip's mother is 33 years old.

solving the equation:
Subtract 5 from both sides:


Divide both sides by 2:

Hence
- Phillip's age is 14 years
