Answer» Answer: let the father's age be = x the sons age be = y sum of their ages = 55 x + y = 55 -------------1 twice of the age of the SON = 2y sum of the age of the father and the twice of the age of the son = 70 x + 2y = 70-----------2 sub eq 1 and 2 x + y = 55 x + 2y = 70 symbol CHANGE then x and -x will be cancelled then -y = -15 y = 15 age of father = x = 55 - y = 55 - 15 = 40 therefore age of father = 40 age of son = 15 I THINK this is the answer............I hope this helps u
