Stefanie's age is 54 and Hannah's age is 18

<h3>How to determine their current ages?</h3>

Let x represent Stefanie's age and y represent Hannah's age

<u>Presently</u>

x = 3y

<u>Four years ago</u>

x - 4 + y - 4 = 28

Substitute x = 3y in the above equation

3y - 4 + y - 4 = 28

Evaluate the like terms

2y = 36

Divide both sides by 2

y = 18

Substitute y = 18 in x = 3y

x = 3 * 18

Evaluate

x = 54

Hence, Stefanie's age is 54 and Hannah's age is 18
