5-4(2x+3)>1-2(3x-7)

12x-(x+4)<-3-(x-2)
.

Answer 1

Explicație pas cu pas:

$5-4(2x+3)>1-2(3x-7) \\ 5 - 8x - 12 > 1 - 6x + 14 \\ - 8x - 7 > - 6x + 15 \\ - 7 - 15 > - 6x + 8x \\ - 22 > 2x \iff 2x < - 22 \\ x < - 22 \div 2 \implies x < - 11$

$12x-(x+4)<-3-(x-2) \\ 12x - x - 4 < - 3 - x + 2 \\ 11x - 4 < - x - 1 \\ 11x + x < - 1 + 4 \\ 12x < 3 \\ x < \frac{3}{12} \iff x < \frac{1}{4}$
