x - 3(x - 1) - (x + 1) = - 3(x - 3)

x -3x + 3 - x -1 = - 3x + 9

x - 3x - x + 3x = - 3 + 1 + 9

0 = 6 

Equazione Impossibile  Ø

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

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

2x + 3x - 6 - x + 1 + x = 2x + 1

2x + 3x - x + x - 2x = 6 - 1 + 1

3x = 6 --->  x = 2

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

2x + 1/2 = 2x + 1/2

2x - 2x = - 1/2 + 1/2

0 = 0

Equazione Indeterminata

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

x - 1/2 = x + 1/2 - 1

x - x = 1/2 + 1/2 - 1

0 = 0

2/3x + 1 = 3/2 + x - 1/3

2/3x - x = 3/2 - 1/3 - 1

-1/3x  = 1/6

x = - 1/2

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

2x - 1/3 = 1/3 - 1/2x - 2/3

2x + 1/2x = 1/3 + 1/3 -2/3

5/2x = 0   --> x = 0

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

x - 3/2 + 2x - 1/3 = 1/2x + 13/6

x + 2x - 1/2x = 3/2 + 1/3 + 13/6

5/2x = 4   -->  x = 8/5

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

x - 2/2 + 3/4 = x - 2/2 + 7/4

x - x = 2/2 - 3/4 - 2/2 + 7/4

0 = 1
