      Solution

      ATQ,

      Let apples with John = x, Paul = y, George = zThen:

      x + y = z + 10 тАжтАжтАж(1)

      y + z = x + 6 тАжтАжтАж(2)

      x + z = 38 тАжтАжтАж(3)

      Add (1), (2), and (3):

      тЖТ (x + y) + (y + z) + (x + z) = z + 10 + x + 6 + 38

      тЖТ 2x + 2y + 2z = x + z + 54

      тЖТ 2(x + y + z) = x + z + 54

      тЖТ From (3), x + z = 38

      тЖТ 2(x + y + z) = 38 + 54 = 92

      тЖТ x + y + z = 46
