Answer:
hi there!
The correct answer to this question is: 80 years old
Step-by-step explanation:
you first need to set up to equations:
in this case: I will use the variable "e" for Ethan and "g" for Geoff
e=10g
g + e = 88
since e = 10g, substitute that into the second equation and you get 10g + g = 88
you add the variables and you get 11g=88 then you divide 11 on both sides and you get 8 so geoff is 8
then you plug 8 back into the second equation and you get ethan's age which is 80
