Решите задачу:

$1) \frac{7x+2}{6}-x \leq \frac{5x+4}{3}-4x|*6\\7x+2-6x \leq 10x+8-24x\\(7-6-10+24)x\leq 8-2\\15x\leq 6\\x\leq \frac{6}{15}\\x\leq \frac{2}{5}\\x\leq 0.4$
$2)\frac{4x+1}{3}-x \ \textgreater \ \frac{x+1}{2}-\frac{x-3}{4}|*12\\16x+4-12x\ \textgreater \ 6x+6-3x+9\\(16-12-6+3)x\ \textgreater \ 6+9-4\\x\ \textgreater \ 11$
$3) \frac{9-5x}{2}-\frac{4x}{3}\ \textless \ x-\frac{3x-1}{6}|*6\\27-15x-8x\ \textless \ 6x-3x+1\\(-15-8-6+3)x\ \textless \ 1-27\\-26x\ \textless \ -26\\x\ \textgreater \ 11$
$4) \frac{5x-3}{4}-\frac{11x}{6}\ \geq \frac{2(1-x)}{3}+\frac{3x}{2}|*12\\15x-9-22x\geq 8-8x+18x\\(15-22+8-18)x\geq 8+9\\-17x\geq 17\\x\leq -1$
