((5·x + 6)/4 - (1 - 3·x)/5)·((1 + x)/3) - x/20·(x - 29/3) =

=(1 - 3·x)/2·((2·x + 1)/5 - (x + 6)/3) + 2/3·x^2

--------------------------------

(37·x + 26)/20·((1 + x)/3) - x/20·((3·x - 29)/3) =

=(1 - 3·x)/2·((x - 27)/15) + 2/3·x^2

-----------------------------------

(x + 1)·(37·x + 26)/60 - x·(3·x - 29)/60 =

=(27 - x)·(3·x - 1)/30 + 2/3·x^2

---------------------------------------

(x + 1)·(37·x + 26) - x·(3·x - 29) =

=(27 - x)·(3·x - 1)·2 + 2/3·x^2·60

-----------------------------------

(37·x^2 + 63·x + 26) - (3·x^2 - 29·x) =

=(- 6·x^2 + 164·x - 54) + 40·x^2

--------------------------------------

34·x^2 + 92·x + 26 = 34·x^2 + 164·x - 54

equazione lineare: soluzione:

x = 10/9
