Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin? Write a systems of equations first, let x=Erin's age and y=Alex's age

X = 15 = Erin's age

Y = 18 = Alex's age

Step-by-step explanation:

X = Erin's age

Y = Alex's age

33 (combined ages) - 3 (how many years Erin is younger than Alex) = 30

30 ÷ 2 = 15

15 + 0 = 15 (Erin's age)

15 + 3 = (Alex's age)

X = 15 = Erin's age

Y = 18 = Alex's age

Check if I'm correct:

15 + 18 = 33

Sorry if wrong! Plz mark brainiest if correct :D Have a great day luv <3
