Sia ? 4 years, 6 months ago

Let the age of mine, my father and my grandfather be 25, 50, and 75 years respectively.

(a) Now, Age of mine = 25 years.
Age of my grandfather = 75 years.
This means my grandfather is thrice times older then me.
∴ Grandfather's age = 3 × My age
If my age is x (= 25) years and then my grandfather's age will be 3x years.
∴ Required linear equation is
Grandfather's age = 3x

(b) Mine age = 25 years.
My Father's age = 50 years.
It means my father is twice of mine age,
∴ Father's age = 2 × My age
Father's age = 2x
This is the Required linear equation of one variables.
