Answer: Christopher is 7 years old.


Step-by-step explanation: If I were Ishaan's age and C were Christopher's age, if Ishaan is 3 times the age of Chris we can do

I=3c

We also know that Ishaan is 14 years older than Chris. So we can set the equation as:

I=14+c

If we insert I=3c into I=14+c, it is

3c=14+c

2c=14

c=7

Therefore, chris is 7 years old.

i = 3c

i = c + 14

set both equations equal to each-other, we can

solve for c, we must.

3c = c + 14

subtract c from both sides, we must.

2c = 14

divide both sides by 2, we must.

c = 7

7 years old, Christopher is.
