John is 36, Jane is 27 When he was 27, she was 18. The algebraic solution to the equation: Let A = John and B = Jane, and time t = A - B (difference in ages) If t years ago, John was twice as old A = 2 (B - t) and substitute A - B for t A = 2B - 2A + 2B 3A = 4B A = 4/3 B and since A + B = 63 4/3 B + B = 63 7/3 B = 63 B = 21 and A = 28
