A + B = 30
3(A+5) = B+5
3A + 15 = 30 - A +5
4A = 20
A = 5
B = 25
A be A's age
B be B's age

Let the age of A be x and B be y years.
Given that sum of ages of A and B is 30 years.
= > x + y = 30
= > x = 30 - y ----- (1)
After 5 years:
= > Age of A = x + 5.
= > Age of B = y + 5.
Given that After 5 years, A will be three times older than B.
= > x + 5 = 3(y + 5)
= > x + 5 = 3y + 15
= > 30 - y + 5 = 3y + 15
= > -y = 3y - 20
= > -4y = -20
= > y = 5.
Substitute y = 5 in (1), we get
= > x = 30 - y
= > x = 30 - 5
= > x = 25.
Therefore,
The ages of A = 25 years.
The age of B = 5 years.
Hope this helps!
