Odpowiedź:
2x-5 = 4x-9
2x-4x=-9+5
-2x = -4
x = 2
9x + 6 = 6x - 3
9x-6x = -3 - 6
3x = -9
x = -3
5(x - 1) - 4(x + 3) - 5 = 3(x - 1)
5x - 5 - 4x - 12 - 5 = 3x -3
x - 22 = 3x - 3
-2x = 19
x = -[tex]\frac{19}{2}[/tex]
x = -9[tex]\frac{1}{2}[/tex]
2x - (x - 2) = 4 - 6x
2x - x + 2 = 4 - 6x
x +2 = 4 - 6x
7x = 2
x = [tex]\frac{2}{7}[/tex]
