Question

after 15 years,salma will be four times as old as she is now. determine her present age​

Answer 1

Let Salma's present age be x

Therefore

x+15 = 4x

3x = 15

x = 5

Therfore her present age is 5 years

Answer 2

Answer:

5

Step-by-step explanation:

let us consider the present age of Salma=x

then the age of Salma after 15 years=x+15------(1)

and also given that age of Salma after 15 years=4x--------(2)

by equivating equation 1 and 2

we get,

x+15=4x

=>4x-x=15

=>3x=15

= x=5
