After 15 yrs, Salma will be four times as old as she is now. Determine her present age.

Let Salma's age be n years.
After 15 years, Salma will be (n + 15) years
Therefore:
n + 15 = 4n
Subtract n from each side of the equation.
n + 15 - n = 4n - n
Combine like terms:
n - n = 0
4n - n = 3n
Therefore:
15 = 3n or
3n = 15
Divide each side by 3
3n/3 = 15/3
n = 5
Therefore:
Salma is 5 years old now.
In 15 years Salma will be (5 + 15) = 20 years.
