1. | x + 8 | = 16
x + 8 = 16
x = 16 - 8
x = 8
atau
- | x + 8 | = 16
x + 8 = -16
x = -16 -8
x = -24
2. |2x + 5| = 8
2x + 5 = 8
2x = 8 -5
2x = 3
x = 3/2
atau
-|2x + 5| = 8
2x + 5 = -8
2x = -8 -5
2x = -13
× = -13/2
3. |3x -3 | = 12
3x -3 = 12
3x = 12 + 3
3x = 15
x = 5
atau
-|3x-3| = 12
3x - 3 = -12
3x = -12 + 3
3x = -9
x = -3
