Question

Sunil is thrice as old as his son. By taking Sunil's age as x years and his son's age as y years, write a linear equation in two variables to represent the statement. Express the equation in the form of ax+by+c=0 and indicate the values of a,b, and c

Answer 1

Explanation:

Let x be Sunil's age and y be his son's age.

Since Sunil is thrice as old as his son, we can write the equation x = 3y.

we could just rearrange the equation x = 3y

as x- 3y = 0

(or)

To express the equation in the form of ax + by + c = 0, need to find the values of a, b, and c.

a = 1

b = -3

c = 0

Therefore, the equation representing the statement "Sunil is thrice as old as his son" is x - 3y = 0.
