Question

Erin is 3 years younger than twice Alex's age. Their ages

combined are 33
years. Write an equation to solve.

Answer 1

X = 15 = Erin's age

Y = 18 = Alex's age

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
