let Rahul father age = x
Rahul age = y
x-5=5y
x-5y-5=0------1
x+y=40
x+y-40=0-------2
by elimination
-6y=-35
y=35/6
x=5+5y
x can be find by solving this
Rahul age = y
x-5=5y
x-5y-5=0------1
x+y=40
x+y-40=0-------2
by elimination
-6y=-35
y=35/6
x=5+5y

Answer:
Five years ago, let father's age be 5x
and let Rahul's age be x
At the present, sum of their ages = 40
→ 5x + 5 + x + 5 = 40 years
→ 6x + 10 = 40
→ 6x = 40 - 10
→ 6x = 30
→ x = 5
Therefore Rahul's age = 5 years
And father's age = 40 - 5 = 35 years
