9(x+8)=9x+8
9x + 72 = 9x + 8
9x - 9x = 8 - 72
0 = - 64
sprzeczne
2,6-0,03x=0,1x
- 0,03x - 0,1x = - 2,6
- 0,13x = - 2,6
x = 2,6/0,13 = 20
0,01x-1=0,1x-0,1
0,01x - 0,1x = - 0,1 + 1
- 0,09x = 0,9
x = - 0,9/0,09 = - 10
(2x-1)*(-2)=1/3x
- 4x + 2 = ⅓x
- 12x + 6 = x
- 12x - x = - 6
- 13x = - 6
x = 6/13
3/4(2-3x)-6
6/4 - 9/4 x = 6
6 - 9x = 24
- 9x = 24 - 6
- 9x = 18
x = - 18/9 = - 2
(1-2x):3=3x
1 - 2x = 9x
9x + 2x = 1
11x = 1
x = 1/11
