Question

My cousin is 3 years older than me. The sum of our ages is 29. How old am I?

Answer 1

13 years.

Step-by-step explanation:

Let my age be x years.

My cousin's age= x+3

Given, the sim if our ages is 29

x+x+3=29

2x+3=29

2x=29-3

2x= 26

x=26/2

x= 13

Therefore, my age is 13 years.

My cousin's age=x+3 = 13+3= 16 years.

13+16=29 Hence, verified.

Answer 2

Answer:

∴ Your age is $16$ years.  

Step-by-step explanation:

• In context to question asked,
• Let, $x$ be your age.
• Age of your cousin = ($x+3$) years
• Sum of ages of both = $29$ years
• According to given condition, the equation becomes,

      $x+x+3=29$

       ∴ $2x+3=29$

             ∴ $2x=29-3$

             ∴ $2x=26$

              ∴ $x=\frac{26}{2}$

               ∴ $x=13$ years

• And your cousin's age = $(x+3)=(13+3)=16$ years
• ∴ Your age is $16$ years.
