Question

form a pair of linear equation in two variables using the following information and solve it graphically 5 years ago Sagar was twice as old as Tiru 10 years later Sagar is will be 10 year more than true age find their present age what was the age of Sagar Ventura was born

Answer 1

Let sagar's present age be x years

Tiru's age be y years

5 years ago

x-5=2(y-5)

x-2y+5=0

Answer 2

Let sagar's present age be x years. Tiru's age be y years. 5 years ago, x-5=2(y-5), x-2y+5=0.

The pair of linear equation is solved by using the formula and thus it takes by present ages.

This is so far identified on median of the data using the given graph. It goes five years ago and this equation is formed finally.
