Question

after 3 year the age of the father will be 3 times the age of his son​

Answer 1

Answer:

So three times son's age subtracted from father's age is equal to 6

Answer 2

Correct Question :

• After 3 year the age of the father will be 3 times the age of his son . write in Linear equation in two variables

Answer :

• x - 3y = 6 is the Linear equation in two variables.

Given :

• After 3 year the age of the father will be 3 times the age of his son

To find :

• Linear equation in two variables

Solution :

• Let the age of father age be x
• Let the age of son age be y

After 3 years,

• Age of father = (x + 3)
• Age of son = (y + 3)

Now , we have to write in Linear equation in two variables :

》(x + 3) = 3(y + 3)

》x + 3 = 3y + 9

》x - 3y = 9 - 3

》x - 3y = 6

Hence , x - 3y = 6 is the Linear equation in two variables

Three times son's age subtracted from father's age is equal to 6

More Explanation :

• The pair of values of the variables x and y which together satisfy each one of the equation is called the Solution for a pair of linear equation
• A pair of linear equation in two variables can be solved using various methods
• A graph of linear equation in two variables is represented by two lines
