5x/2 - x/3 - 2 = 8/3 + x
5/2x - 1/3x  -x = 8/3 +2
15/6x -2/6x -6/6x =  8/3 +6/3
7/6x = 14/3
x = 14/3 * 6/7
x = 14*6 / 3*7
x = 4

5x/2 - x/3 - 2 = 8/3 + x
5x/2 - x/3 - 2 - 8/3 - x = 0
5x/2 - x/3 - x = 14/3
(5/2 - 1/3 - 1)x = 14/3
7/6x = 14/3
x = 14/3 : 7/6
x = 14/3 x 6/7
x = (2 x 7)/3 x (2 x 3)/7
x = 2 x 2
x = 4
