Explicație pas cu pas:
(2x - 3)/(x - 5) < 1/2
2(2x - 3) < x - 5
4x - 6 < x - 5
4x - x < 6 - 5
3x < 1
x < 1/3
_________________
(5 + x)/x < 2
5 + x < 2x
2x - x > 5
x > 5
__________________
(x - 11)/(1 - 2x) > 3
x - 11 > 3(1 - 2x)
x - 11 > 3 - 6x
x + 6x > 3 + 11
7x > 14
x > 14/7
x > 2
____________________
(4x - 3)/3x ≥ 1
4x - 3 ≥ 3x
4x - 3x ≥ 3
x ≥ 3
______________________
4x/(x - 1) < 4/3 - 1/(x - 1)
4x/(x - 1) + 1/(x - 1) < 4/3
(4x + 1)/(x - 1) < 4/3
3(4x + 1) < 4(x - 1)
12x + 3 < 4x - 4
12x - 4x < -3 - 4
8x < -7
x < -7/8
