Answer» 1Step-by-step explanation:LET Ron’s present age be x. Then AARON’s present age = x - 5After 4 years Ron’s age = x + 4, Aaron’s age x - 5 + 4. ACCORDING to the question; Ron will be twice as OLD as Aaron. THEREFORE, x + 4 = 2(x - 5 + 4) ⇒ x + 4 = 2(x - 1) ⇒ x + 4 = 2x - 2⇒ x + 4 = 2x - 2⇒ x - 2x = -2 - 4⇒ -x = -6⇒ x = 6Therefore, Aaron’s present age = x - 5 = 6 - 5 = 1 |
