Пошаговое объяснение:

$\displaystyle\\\frac{x^2-3x-5}{x-4} +\frac{x^2-6x+3}{x-6} \leq 2x+1\\\\\\\frac{x^2-4x+x-5}{x-4} +\frac{x^2-6x+3}{x-6} \leq 2x+1\\\\\\\frac{x(x-4)}{x-4}+\frac{x-5}{x-4} +\frac{x(x-6)}{x-6} +\frac{3}{x-6} \leq 2x+1\\\\\\x+\frac{x-5}{x-4} +x+\frac{3}{x-6} \leq 2x+1\\\\\\\frac{x-5}{x-4} +\frac{3}{x-6} -1\leq 0\\\\\\\frac{(x-5)(x-6)+3(x-4)-(x-4)(x-6)}{(x-4)(x-6)} \leq 0\\\\\frac{x^2-5x-6x+30+3x-12-x^2+4x+6x-24}{(x-4)(x-6)} \leq 0\\\\\frac{2x-6}{(x-4)(x-6)} \leq 0~\Leftrightarrow~\frac{x-3}{(x-4)(x-6)} \leq 0$
