Answer:
40 and 10
Step-by-step explanation:
let the present age of the father be x and that of the son be y,
taking the case of four years ago,
...(1)
taking the case of ten years in future,
...(2)
now using the elimination method on eq(1) and eq(2) by multiplying eq(1) by 2 and subtracting eq(2) from eq(1),
(substitute this value in eq(1))
so the father's current age is 40 and the son's current age is 10
