Question 1
Levi is twice as old as Raelynn was 7 years ago. The difference between their ages is 15 years. How old is Levi?
Let Raelynn's current age = x
Then 7 years ago, Raelynn was (x - 7)
Levi = 2(x - 7) = 2x - 14
Difference: Levi - x = (2x - 14) - x = x - 14
Given difference = 15
So x - 14 = 15 → x = 29 = 29
Then Levi = 2(29 - 7) = 44
Then 7 years ago, Raelynn was (x - 7)
Levi = 2(x - 7) = 2x - 14
Difference: Levi - x = (2x - 14) - x = x - 14
Given difference = 15
So x - 14 = 15 → x = 29 = 29
Then Levi = 2(29 - 7) = 44
