Ex. 13 b), c).......

Answer 1

Răspuns

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
