Ответ:
- \(\frac{x}{7}+x>4\Rightarrow\frac{8x}{7}>4\Rightarrow x>3.5\).
- \(\frac{5x}{3}+1\le\frac{x+1}{3}\Rightarrow5x+3\le x+1\Rightarrow x\le-0.5\).
- \(\frac{4x-2-(6x-2)}5\ge3\Rightarrow-\frac{2x}{5}\ge3\Rightarrow x\le-7.5\).
- \(\frac{x}{5}-\frac{x+3}{7}\ge-1\Rightarrow7x-5x-15\ge-35\Rightarrow x\ge-10\).
- \(\frac{7-x}{2}\le\frac{x+1}{3}+2\Rightarrow21-3x\le2x+14\Rightarrow x\ge3.8\).
- \(\frac{-x-2}{5}+\frac{x}{3}\ge\frac7{15}\Rightarrow-3x-6+5x\ge7\Rightarrow x\ge6.5\).
Ответ: а) \(x>3.5\); б) \(x\le-0.5\); в) \(x\le-7.5\); г) \(x\ge-10\); д) \(x\ge3.8\); е) \(x\ge6.5\).
