Помогите решить пример!
5х/12 - x-2/4 + x+1/3 <0

Answer 1

$\frac{5x}{12} - \frac{x - 2}{4} + \frac{x + 1}{3} < 0 \\ \\ \frac{5x}{12} - \frac{3(x - 2)}{12} + \frac{4(x + 1)}{12} < 0 \\ \\ \frac{5x - 3x + 6 + 4x + 4}{12} < 0 \\ \\ \frac{6x + 10}{12} < 0 \\ \\ 6x + 10 < 0 \times 12 \\ \\ 6x + 10 < 0 \\ \\ 6x < 0 - 10 \\ \\ 6x < - 10 \\ \\ x < - \frac{10}{6} \\ \\ x < - \frac{5}{3} \\ \\ x < - 1 \frac{2}{3}$
