m - 21 = c
(m+6) = 5(c+6)
(m+6) = 5(m - 21+6)
4m = 6 + 5*21 - 5*6 = 81 => m = 81/4 = 20.25 years
mum is 20.25 years
child is - 0.75 year

If you solve the equation you get that the mom is 20.25 and that the kid is -.75, which is negative 9 months, so it has not been conceived yet. There's no dad (pregnancy is 40-41 weeks which is a bit more than 9 months), or the dad is knocking the mom up right now, assuming that the kid will be a bit premature. But there's no kid either-it's either a work in progress, a fertilized egg cell or a zygote.
If the mom is looking for a dad to knock her up , she should wait a few more years- just for algebra's sake

Mum is 21 older than child. After 6 years, Mum will be 5 times older than child
21/(5-1)=5.25
5.25-6=-0.75
5.25*5=26.25
26.25-6=20.25
So Mum is 20.25 yrs old and child is... -0.75 yrs old!!! You have just entered minusland!!!
Where is Dad???
Since 0.75yrs =9months, and assuming the child was born exactly after 9 months, then Dad must be on the bed.
(Your question is nonsensical)
