Therefore, the present age of the father is 45 years. Solve (1) and (2) to find the value of the unknown. Twice the sum of ages of two sons -> 2(y + 10)Įquations related to the second information using x and y is (Here we have added 5 two times.The reason is there are two sons) Sum of the ages of his two sons -> y + 5 + 5 = y + 10 Thrice the sum of the ages of his two sons -> 3yĮquation related to the first information using x and y isĪfter 5 years, his age would be twice the sum of their ages.Īge of the father after 5 years -> (x + 5) ![]() The age of the father is thrice the sum of the ages of his two sons. Translate the given information as mathematical equation using x and y. Let y be the sum of present ages of two sons.īecause that is the target of the question.
