Question

Решите неравенство   4\7х+1\6(знак больше или равно) 3\14+2\3х

Answer 1

$<var>\frac{4}{7}x+\frac{1}{6}\geq \frac{3}{14}+\frac{2}{3}x\\ \frac{4}{7}x-\frac{2}{3}x\geq \frac{3}{14}+\frac{1}{6}\\ \frac{12}{21}x-\frac{14}{21}x\geq \frac{9}{42}+\frac{7}{42}\\ -\frac{2}{21}x\geq \frac{16}{42}\\ x\leq-4</var>$
