Question

arnav's father is 49year old . he is nine year older than four times arnav's age .set up equation to final arnav's age

Answer 1

Hey Mate !!

Here's your answer !!

Let Arnav's age be 'x'

So  Arnav's father's age IS 49 years.
 
Given: Arnav's father's age = 4 times Arnav's age + 9 years

Equation would be = 

= 49 = 4(x) + 9

= 49 = 4x + 9

= 4x = 49 - 9

= 4x = 40

= x = 40 / 4

=> x = 10

So Arnav's age is 10 years.

Hope it helps !!

Cheers !!
