nie wiem czy czasem nie wkradły mi się jakieś błędy, w 5 podpunkcie. Za które oczywiście przepraszam :)
1) 3x -5 = 4 +2x
3x -2x = 4 +5
x = 9
2) -5x -17 = -9x +3
-5x + 9x = 3 +17
4x = 20 /:4
x = 5
3) - 5x +10 = -2x -8
-5x +2x = -8 -10

x = 6
4) (4-2x)-(x+3) = (x-5)+(-3-x)
4 -2x -x -3 = x -5 -3 -x

5) (3-2x)+(3x+4)= -(3 -2x)+ (5x+ 4)
