The father is always 28 years older than his son, so the equation can be written:. (1) father = son + 28 at all times after birth. at some point the father is three times greater than thave a son as well:. (2) father = 3son So that we can combine (1) and (2) equations as:. 3son = son + 28 2son = 28 son = 14. so when the son is 14 the father is 28 years older which is 42 and 3 times older than 14 years.
