(a million) If 5 is extra to the smaller selection,the end result's comparable to a million/2 of the greater suitable selection (5 + Y) = a million/2 X ... (2) Multiply the two components of the equation (2) via 2, 2 (5 + Y) = X ... (3) substitute (3) into (a million) 2 (5 + Y) - Y = 31 10 + 2Y - Y = 31 Y = 31 - 10 Y = 21 ... (4) substitute (4) into (a million), X - 21 = 31 X = fifty two The sum of the two numbers is, X + Y = fifty two + 21 answer = seventy 3
