Answer 1

Let the age of Arnav be x
Arnav's father is 49 years

Equation set up would be
Father =4x+9=49
As Arnav's father is 9year older than 4times the age of Arnav

4x+9=49
4x=49-9
4x=40
x=40/4
x=10

Arnav's age is 10 years

Answer 2

Let arnav's age = X
Arnav's Father Age = 49 years = (4 x X) + 9
49-9 = 4 x X
40 = 4 x X
40÷ 4 = X
10 = X
Arnav's Age = 10 years
