conversations.value: I need help with this problem:
  Juanico is 4 years less than half the age of Gladys. If Gladys will be 40 years old ten years from now, calculate Juanico's age 30 years from now.

conversations.value: If Gladys will be 40 years old ten years from now, she is 40-10= 30 years old currently.
  Juanico is 4 years less than half the age of Gladys, meaning he is 4 years younger than 1/2*30 = 15 years.
  Juanico's age is 15-4 =11 years.
  Juanico's age 30 years from now will be 30+11 = 41 years.
