Could I please get some help with the problem below?

Question

Cody is twice as old as Evan. Three years ago the sum of their ages was 27. Find the age of Cody now.

Answer 1

Now:

E represents Evan's age, 2E represents Cody's age

Then

E - 3 represents Even's age, 2E - 3 represents Cody's age

Equation:

(E - 3) + (2E - 3) = 27

Can you solve for E and answer?
