Let John’s current age be 5x years and Mary’s current age be 3x years. According to the problem, five years ago: John's age = 5x - 5 Mary's age = 3x - 5 The sum of their ages five years ago was 38 years: (5x - 5) + (3x - 5) = 38 Simplifying the equation: 5x - 5 + 3x - 5 = 38 8x - 10 = 38 8x = 48 x = 6 Now, substituting x back to find their ages: John's age = 5x = 5(6) = 30 years Mary's age = 3x = 3(6) = 18 years
