Question

Adele is 5 years older than Timothy. In three years, Timothy will be 2/3 of Adele’s age. What is Adele’s current age?

Answer 1

A = 5 + T
T+ 3 = 2/3 ( A + 3) 
So the answer would be:
Adele is12 years old
And...
Timothy is 7 years old

Good luck~ Sans

Answer 2

Suppose,
Timothy age = x
Adele age = x+5

After three years, there ages will be: Timothy = x+3
Adele = x+5+3 = x+8

A.T.Q,
x+8 * 2/3 = x+3
2x+16/3 = x+3
2x+16 = 3x+9
3x-2x = 16-9
x = 7

Adele's current age = x+5 = 7+5 = 12

So, your final answer is 12
