vì \(VT\ge0\Rightarrow VP\ge0\)
\(\Rightarrow x\ge0\)
\(\Leftrightarrow\left|x+1\right|+\left|x+2\right|+...+\left|x+100\right|=101x\)
\(\Leftrightarrow x+1+x+2+..+x+100=101x\)
\(\Leftrightarrow100x+\left(1+2+3+...+100\right)=101x\)
\(\Leftrightarrow100x-101x=5050\)
\(\Leftrightarrow-x=5050\Rightarrow x=5050\left(ktm\right)\)
