Question

Obtain a pair of linear equation in two variable from following information:-
Mother tells her son," five years ago I was five times old as you were. After 10 years I will be two times as old as you.

Answer 1

Answer:

let mother's age = x

    son's age = y

x = 5y - 20

x = 2y + 10

Answer 2

Step-by-step explanation:

moms present age is x

sons age is y

Five years ago :

mom : x - 5

son : y -5

so, x - 5 = 5( y -5)

x- 5= 5y - 25

x = 5y - 20

10 years after from present:

mom: x + 10

son: y + 10

so, x + 10 = 2(y + 10)

x = y + 10
