Vì \(\left|x+2\right|\ge0;\left|x+4\right|\ge0;\left|x+8\right|\ge0\Leftrightarrow2021x\ge0\Leftrightarrow x\ge0\)

\(\Rightarrow\left|x+2\right|=x+2;\left|x+4\right|=x+4;\left|x+8\right|=x+8\)

\(\Rightarrow x+2+x+4+x+8=2021x\)

\(\Leftrightarrow3x+14=2021x\)

\(\Leftrightarrow2021x-3x=14\)

\(\Leftrightarrow2018x=14\)

Từ đó tìm được x nha

\(\left|\frac{x+2}{5}\right|=\left|\frac{2x-1}{3}\right|\)

<=> \(\orbr{\begin{cases}\frac{x+2}{5}=\frac{2x-1}{3}\\\frac{x+2}{5}=\frac{1-2x}{3}\end{cases}}\Leftrightarrow\orbr{\begin{cases}3\left(x+2\right)=5\left(2x-1\right)\\3\left(x+2\right)=5\left(1-2x\right)\end{cases}}\Leftrightarrow\orbr{\begin{cases}7x=11\\13x=-1\end{cases}}\Leftrightarrow\orbr{\begin{cases}x=\frac{11}{7}\\x=-\frac{1}{13}\end{cases}}\)

Vậy \(x\in\left\{\frac{11}{7};-\frac{1}{13}\right\}\)
