A mother is 21 years older than her son, in 6 years the kid will be 5 times younger than his mother. Where is the father?
The kid has X years
The mother has Y years
The mother is 21 years older than her son X+21=Y
In 6 years the kid will be 5 times younger than his mother
5(X+6)=Y+6
5X+30=X+21+6
5X-X+21+6-30
4X=-3
x=-3/4
the kid is -9 months old
So is the father on top of the mother having sex?

Your math looks right to me. Also, the mother would be 20, not 12, becuase the mother is 21 yrs older than the son. Also, this must be the answer, becuase otherwise we'd have no idea where that father is.

Plug it all back in and it checks out. If the son is currently -3/4, then the mother is 20.25 years old.
six years from now, the child will be 5.25 years old and mom will be 26.25 years old. 5.25 x 5 = 26.25,so yes, the equation is solved.
A typo from your teacher is as good a place as any to start getting creative with metaphysics, but in the end, it's just a typo from your teacher. Good luck...sounds like you'll need it.

No it's not true because if the kid is negative 9 months old then the mother is 12 and she wouldn't get pregnant.Atleast I hope not!

Makes sense. I'm guessing thi is a riddle, and if the kid were any other age it would be impossible to tell where the father is.

Everything's good with your math. The location of the father is a little matter of debate, buit regardless, he's probably near his sperm.
Funny joke, too.

^ You think 12 year old girls can't get pregnant? Think again.
Funny equation, I'll have to remember that one!

Hahaha, yay for math!
I found no mistake, so you're probably right.

Your Equation itself is wrong. Where did you get it ?
