Answer: Ishann is 21 years old.

Explanation:

In this situation, we will represent Ishaan age by the variable y and we will represent Christopher's age by x.

Ishaan is 3 times as old as Christopher and that can be represented by the equation, y = 3x

He is also 14 years older, and it can also be represented by the equation,

y = x + 14.

y= 3x

y = x + 14

Using both equations, substitute the value of y in one of the equations into the other.

x + 14 = 3x Solve for x .

-x -x

14 = 2x

x = 7

This means that Christopher is 7 years old.

To solve for Ishaan's age , input the value of x into one of the equations.

y = 3(7)

y = 21.
