a man is 22 years older than his son . in three years , his age will be thrice the age of his son . the present age of this son is
"let ' s son age is x , then father age is x + 22 . = > 3 ( x + 3 ) = ( x + 22 + 3 ) = > 3 x + 9 = x + 25 = > 2 x = 16 years = 8 years answer : d"
divide(subtract(22, subtract(multiply(const_2, const_2), const_2)), subtract(const_2, const_1))
