It's a brainaliest question!!!
Find the linear equation in two variables of given below

Ravish tells his daughter arushi, 7 years ago I was 7 times as old as you, also 3 years from now I shall be 3 times as old as you will be. If present ages of them are x and y then find equation

Answer 1

hi friend here is your answer
✌✌✌
As the ages are given of ravish is x and arushi is y then the following equation comes,

(7-x)7y (3+3y)

hope it will help you
mark it as brilliant answer

Answer 2

Given the present ages of Ravish and Arushi as x and y respectively.
Seven years ago, 
age of Ravish = x - 7 years 
age of Arushi = y - 7 years
Given age of Ravish is seven times the age of arushi, so 
x - 7 = 7(y-7)
x-7= 7y-49
x-7-7y+49 = 0
x-7y+42 = 0 --------(1)

Also the age of Ravish three years from now = x+3 years
and the age of Arushi = y+3 years

Given three years from now age of Ravish is three times the age of Arushi.
x + 3 = 3(y+3)
x+3-3y-9= 0
x-3y-6= 0 --------(2)

so 1 and 2 eqns represent the linear eqns in two variables for the given problem.

Hope this helps you out.
