Question

|x+8|=10

Answer 1

\(\left|x+8\right|=10\)

\(\Rightarrow\left[{}\begin{matrix}x+8=-10\\x+8=10\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=-10-8\\x=10-8\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=-18\\x=2\end{matrix}\right.\)

Vậy...

Answer 2

ta có; |x+8|=10

=>\(\left[{}\begin{matrix}x+8=10\\x+8=-10\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=10-8\\x=-10-8\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=2\\x=-18\end{matrix}\right.\)

Vậy x=2 hoặc x=-18
