a)
| x | = 3
x = 3 v x = - 3
b)
| x - 1 | = 5
x - 1 = 5 v x - 1 = -5
x = 6 v x = - 4
c)
| - 4 - x | = 110
- 4 - x = 110 v - 4 - x = - 110
x = - 114 v x = 106
d)
| x + 26 | = 21
x + 26 = 21 v x + 26 = - 21
x = - 5 v x = - 47
e)
| 2x - 10 | = 28
2x - 10 = 28 v 2x - 10 = - 28
2x = 38 v 2x = - 18
x = 19 v x = - 9
f)
1 - | - 34 + x| = - 56
1 + 34 - x = - 56 v 1 + 34 - x = 56
x = 91 v x = - 21
