Question

Hema’s age is 4 times the age of Mary. Write a linear equation in two variables to represent this information.

Answer 1

Hint: In order to write a linear equation for the given, consider two variables x and y and express the given in form of these two variables to obtain a relation.

Complete step-by-step answer:
Given Data, Hema’s age is 4 times the age of Mary.
Let the age of Hema is x years and Mary is y years.
Then as per given Hema’s age is 4 times the age of Mary.
Hence, x = 4y
$\Rightarrow$ x – 4y = 0.

Note: In order to solve questions of this type the key is to express the given, using the variables and applying the relations mentioned in the question. Then we get a linear equation with the given conditions.
