Answer (2)
Reagan (R) Sara (S) Lauren (L)
R-3 (Reagan's age 3 years ago...) we have 3 equations with 3 variables:
R-3 = 3 * (S-3) -> R -3 = 3S - 9 -> R = 3S -6 R-3 = (L-3) / 2 -> 2R -6 = L - 3 -> L = 2R -3 R+3 = 2 * (S+3) -> R +3 = 2S + 6 -> R = 2S +3
3S - 6 = 2S + 3 -> S = 9 R = 2 * 9 +3 = 21 L = 2 * 21 -3 = 39
Reagan is 21 Sara is 9 Lauren is 39
3 years ago - Reagan was 18 - 3 X Sara who was 6 3 years from now - Reagan will be 24 - 2 X Sara who will be 12
Reagan is currently 21 years old, Sarah is 9 years old, and Lauren is 39 years old. This was determined using equations based on their ages relative to each other both three years ago and three years in the future. All calculations were verified and confirmed to be accurate.
