(6 - 1 / 2) - (3 - X / 3) = 7 - (2X - X / 2)

(5 / 2) - (3 - X / 3) = 7 - (X / 2)

(15 - 3 - X / 6) = (14 - X / 2)

2(12 - X) = (14 - X)6

24 - 2X = 84 - 6X

24 - 84 = 2X - 6X - 60 = - 4X

60 / 4 = X

15 = X.

(6 - 1 / 2) - (3 - X / 3) = 7 - (2X - X / 2)

(5 / 2) - (3 - X / 3) = 7 - (X / 2)

(15 - 3 - X / 6) = (14 - X / 2)

2(12 - X) = (14 - X)6

24 - 2X = 84 - 6X

24 - 84 = 2X - 6X - 60 = - 4X

60 / 4 = X

15 = X.
