[tex] |2x - 1| < x + 1 \\ 2x - 1 - x < 1, \: 2x - 1 \geqslant 0 \\ - (2x - 1) - x < 1, 2x - 1 < 0 \\ x < 2, x \geqslant \frac{1}{2} \\ x > 0, x < \frac{1}{2} \\ yg \: d \: jawabannya[/tex]

-(x+1) < 2x - 1 < x + 1

-x - 1 < 2x - 1
-x - 2x < -1 + 1
-3x < 0
x > 0/-3
x > 0

2x - 1 < x + 1
2x - x < 1 + 1
x < 2

0 < x < 2
