Xavier is one year more than twice the age of Youji. Four years ago, Xavier was three times as old as Youji. Which system of equations below could be used to solve for x , Xavier's present age, and y , Youji's present age? X = 2y + 1 x + 4 = 3(y + 4) x = 2y + 1 x – 4 = 3(y – 4) x = 2(y + 1) x + 4 = 3(y + 4) x = 2(y + 1) x – 4 = 3(y – 4)
