\(\Rightarrow\)trị tuyệt đối 3x-2= -x +9-5=-x+4
\(\Rightarrow\hept{\begin{cases}3x-2=-x+4\Rightarrow\\3x-2=x-4\Rightarrow\end{cases}\hept{\begin{cases}x=loại\\x=-1\end{cases}}}\)
\(\Rightarrow\hept{\begin{cases}3x-2=-x+4\Rightarrow\\3x-2=x-4\Rightarrow\end{cases}\hept{\begin{cases}x=loại\\x=-1\end{cases}}}\)
\(\left|3x-2\right|+5=x+9\)
\(\Leftrightarrow\left|3x-2\right|=x+9-5\)
\(\Leftrightarrow\left|3x-2\right|=x+4\)
\(\Leftrightarrow\orbr{\begin{cases}3x-2=x+4\\3x-2=4-x\end{cases}}\Leftrightarrow\orbr{\begin{cases}x=3\\x=\varnothing\end{cases}}\)
Vậy x = 3
