Dear student

Let the age = x and y where x>y

Now
x -y = 8

x -15 = 3(y -15)
x -15 = 3y - 45
x -3y = -30

Now solve the equations
2y = 38
Hence y = 19 years and x = 27 years

Let,
Firstperson age=x years,2nd person age=y years
And x>y,
ATQ:-
x-y=8
So x=8+y______(1)
Also,
x-15=2(y-15)_____(2)
Put x=8+y in (2),then,we have,
y+8-15=2y-30
=> y-7=2y-30
=>y=23
Now,x=8+y=31

So 1st person age=31years
2nd person age=23 years
