-------------
The age difference is 16 years.
3x at 24 & 8
---------------
age + 16 = 3*age

Hi,
My age is 26, my cousin age is 10. At what age will we be when I am three times his age?
Let x represent number of years that happens
26 + x = 3(10+x)
-4 = 2x
-2 = x
happened 2 years ago at ages: 24 and 8
Answer by jim_thompson5910(35256)  (Show Source):
You can put this solution on YOUR website! Let x = number of years
So in x years, you will be 26+x and your cousin will be 10+x
You want to know when you'll be 3 times his age. So ...
Your age in x years = 3*(Cousin's age in x years)
26+x = 3*(10+x)
So the equation is 26+x = 3*(10+x)
-----------------------------------------------------------------------
Let's solve for x
26+x = 3*(10+x)
26+x = 30+3x
26-30 = 3x-x
-4 = 2x
-4/2 = x
-2 = x
x = -2
So because we got a negative number, you will NEVER be 3 times your cousins age after this point in time.
The result of -2 means you WERE 3 times his age 2 years ago since you were 26-2 = 24 yrs old and your cousin was 10-2 = 8 yrs old (notice how 24 = 8*3).
So after this point in time, you'll never be 3 times your cousin's age (since it only happens once).
