Explicație pas cu pas:
(x-1)/4 + (x+3)/2 < 1 - x/6
(x - 1)/4 + (2x + 6)/4 < (6 - x)/6
(x - 1 + 2x + 6)/4 < (6 - x)/6
(3x + 5)/4 < (6 - x)/6
3(3x + 5)/12 < 2(6 - x)/12
3(3x + 5) < 2(6 - x)
9x + 15 < 12 - 2x
11x < -3
x < -3/11
______________
(x - 3)(x - 6) < (x - 1)(x - 2)
x^2 - 6x - 3x + 18 < x^2 -2x - x + 2
-9x + 18 < -3x + 2
16 < 6x
x > 16/6
x > 8/3
