Question

4 years ago age of a mother was 3 times the age of a Daughter write a linear equation to represent this situation.

Answer 1

Heya mate,
here is your answer:

4 YEARS AGO

let the age of the Daughter = x

then according to the question,
since the mother is 3 times the age of Daughter So,
age of the mother = 3 × x = 3x

then, PRESENT AGE

of the daughter = x + 4
of the mother = 3x + 4

Hence a linear equation for this situation is

x + 4 = 3x + 4

=> 4 - 4 = 3x -x

=> 0 = 2x

=> 2x = 0

=> x = ½

Hope this helps
