X - (-3x (x-1) - x) / x=2 what is x?

First do the disttibutive between - 3x (x-1)

= - 3x^2 + 3x

Then stay:

x - (-3x (x-1) - x) / x = 2

x - (-3x^2+3x-x) / x = 2

Now we sum 3x-x = 2x

X - (-3x^2 + 2x) / x = 2

x + (3x^2 - 2x) / x = 2

x+3x - 2 = 2 4x - 2 = 2 4x = 4 x = 1 Answer = {x e R / x = 1}
