Her nephew is 7.

Hope this helps!
her nephew is 7 years old 

if shes 8 years older then twice his age then you would subtract 8 from her age like so 22 - 8 = 14 
then if he is half of her age minus 8 then you would take the last answer you got and divide it in like so 14/2 = 7 
you get 7 making his age 7
