manca l'ultima parte..inseriscila nei dettagli aggiuntivi.
x^2 - 1/16 - (x^2 + 1/4 + x) - x/2 + 1 = 13/48 - (2x+1)/6
x^2 - 1/16 - x^2 - 1/4 - x - x/2 + 1 = 13/48 - (2x+1)/6
mcm = 48. Moltiplico per 48 primo e secondo membro
- 3 - 12 - 48x - 24x + 48 = 13 - 8(2x+1)
- 72x + 33 = 13 - 16x - 8
- 72 x + 16 x = 13 - 8 - 33
- 56x = - 28
56x = 28
x = 28/56 = 1/2
