|5-x|-17=13
\(\Rightarrow\left|5-x\right|=13+17\)
\(\Rightarrow\left|5-x\right|=30\)
\(\Rightarrow\left[{}\begin{matrix}5-x=30\\5-x=-30\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}x=5-30\\x=5-\left(-30\right)\end{matrix}\right.\)
\(\Rightarrow\left[{}\begin{matrix}x=-25\\x=35\end{matrix}\right.\)
vậy x=-25 hoặc x=35
chúc bn học tốt
