Answer by rimjhim.tomar(21)   (Show Source):
You can put this solution on YOUR website! let Ethan be x years old.
given that Ethan's dad is 10 years older than twice Ethans age,
then Ethan's dad is 2(x)+10.
but given that Ethan's dad is 30 yrs old,
we get,
2x+10=30
2x=20
x=10
Ethan is 10 years old.
