Answer 2

Concept:

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

Given:

A father who is 36 years old says to his son, “I was as old as you when you were born

Find:

What was the age of the son, 5 years ago?

Solution:

Let the age of the son be x years

According to the question,

x=36-x

⇒2x=36years

⇒x=18 years

age of son before 5 years=x-5

                                          =18-5

                                          =13 years

Therefore, the age of son 5 years ago =13 years
