You will need to write this out in a formula.
So you can let Timothy's age be x.
So you will start your formula out as x+5.
Now you have to look age of Timothy after a 3 year period.
So you will then write out a another formula (basically adding to yours)
(x+3)=2/3(x+5+3) - a basic algebra formula format with the information provided.
Then you must solve the equation. Remember you want to use your rules (PEMDAS).
X+3=2/3(x+8)
x+3=2/3+16/3
x-2/3x=16/3-3
x/3=7/3
when you simplify that you get -> x=7.
So your answer is
Adele's current age is 12 years old
Timothy's current age is 7 years old
