Question

3. Form a pair of linear equations in two variables using the following
Information and solve it graphically.
Five years ago, Sagar was twice as old as Tiru. Ten years later, Sagar's age
will be ten years more than Tiru's age. Find their present ages. ​

Answer 1

Answer:

let the age of sagar be x

and, tinu be y

then, according to the question

x=2y

five year ago,

(x-5)=2(y-5)

x-2y=5.....(1)

and,x=y+10

ten years later,

(x+10)=(y+10+10)

x-y=10........(2)

then solve by eliminate method,

x-y=10

x-2y=5

so, we get y=15and x=15

the present age of sgar is 15year and tinu is 5Year

I hope this answer help you
