\(\left|x-3\right|+\left|x-5\right|=2\)2
TH1 Nếu \(x\ge5\)thì
\(\left|x-3\right|+\left|x-5\right|=2\)
\(\Leftrightarrow x-3+x-5=2\)
\(\Leftrightarrow2x-8=2\)
\(\Leftrightarrow2x=10\)
\(\Leftrightarrow x=5\)
TH2 Nếu \(x< 5\)thì
\(\left|x-3\right|+\left|x-5\right|=2\)
\(\Leftrightarrow3-x+5-x=2\)
\(\Leftrightarrow-2x+8=2\)
\(\Leftrightarrow-2x=-6\)
\(\Leftrightarrow x=3\)
