20б Реши неравенство (7/13)^3x−1/x -1 ≥ 169/49

$(\frac{7}{13})^{\frac{3x-1}{x}-1 }\geq\frac{169}{49}\\\\(\frac{7}{13})^{\frac{3x-1}{x}-1 }\geq(\frac{7}{13})^{-2}\\\\0<\frac{7}{13}<1\Rightarrow \frac{3x-1}{x}-1\leq-2\\\\\frac{3x-1}{x}+1\leq0\\\\\frac{3x-1+x}{x}\leq0\\\\\frac{4x-1}{x}\leq0\\\\x(x-0,25)\leq 0,x\neq 0$
