Odpowiedź:
3x + 4 = -5x - 1
3x + 5x = -1 - 4
8x = -5 /:8
x = -5/8
6x +5 = 4x
6x - 4x = -5
2x = -5 /:2
x = -5/2 = -2 1/2
-2x + 2 = -7
-2x = -7 - 2 /:(-2)
x = 9/2 = 4 1/2
x/3 + 1 = 5/6 + x/2
1/3x - 1/2x = 5/6 - 1
2/6x - 3/6x = -1/6
-1/6x = -1/6 /*(-6)
x = 1
x + 2/9 + x - 1/3 = 1
2x = 1 - 2/9 + 1/3 /:2
x = 1 - 2/9 + 3/9 = 1 + 1/9 = 1 1/9
