Question

The age of Joseph is one half time the age of John. Express this statement as a linear equation in two variables.

Answer 1

Let the age of Joseph be x years and age of John be y years. Then, according to question, the equation will be
x= 1/2y

Answer 2

Hi there !!!

Age of Joseph = y

Age of John = x = half the age of Joseph = 1/2y

x = 1/2y

Or

We can also write ,

Joseph's age is 2 times John's age

Joseph's age = x

John's age = y

x = 2y
