\(|5-x|-17=13\)

\(|5-x|=30\)

Answer 2

[Nguyễn Thanh Liêm]

|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
