Let f:R−{0}→Rf: \mathbb{R}-\{0\} \rightarrow \mathbb{R}f:R−{0}→R be a function such that f(x)−6f(1x)=353x−52f(x)-6 f\left(\frac{1}{x}\right)=\frac{35}{3 x}-\frac{5}{2}f(x)−6f(x1​)=3x35​−25​. If the lim⁡x→0(1αx+f(x))=β;α,β∈R\lim\limits _{x \rightarrow 0}\left(\frac{1}{\alpha x}+f(x)\right)=\beta ; \alpha, \beta \in \mathbb{R}x→0lim​(αx1​+f(x))=β;α,β∈R, then α+2β\alpha+2 \betaα+2β is equal to
