é un'equazione di primo grado
((6x - x + 6)/6) * [ 1/3 (x^2 - 5/3 x + 25/36) - (2x - 1)/3 * ((9x - 6 - 6x + 2)/6) - x/18 ] = 1/48
(5x + 6)/6 * [ 1/3 x^2 - 5/9x + 25/108 - (2x-1)(3x - 4)/18 - x/18 ] = 1/48
(5x + 6)/6 * [ (36x^2 - 60x + 25 - 6(6x^2 - 11x + 4) - 6x ] = 108/48
(5x + 6) * ( -60x + 25 + 66x - 24 - 6x ) = 648/48
(5x + 6)* 1 = 27/2
5x = 27/2 - 6 = (27-12)/2
x = 15/2 * 1/5
x = 3/2
