\(\left|x-2\right|=3\)
\(\Rightarrow\) \(\left[{}\begin{matrix}x-2=3\\x-2=-3\end{matrix}\right.\)
\(\Rightarrow\) \(\left[{}\begin{matrix}x=3+2\\x=-3+2\end{matrix}\right.\)
\(\Rightarrow\) \(\left[{}\begin{matrix}x=5\\x=-1\end{matrix}\right.\)
\(\left|x-2\right|=3\Leftrightarrow\left[{}\begin{matrix}x-2=3\\x-2=-3\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x-5\\x=-1\end{matrix}\right.\)
|x-2|=3
=> x-2=3 hoặc x-2=(-3)
=>x= 3+2 hoặc x= (-3)+2
=>x=5 hoặc x= -1
Vậy x=5 hoặc x= -1
Chúc bn hk tốt!!
/ x - 2 / = 3
<=> x - 2 =3 hoặc x - 2 = -3
<=> x = 3 + 2 hoặc x = (-3) + 2
<=> x = 5 hoặc x = -1
| x-2 | = 3
\(\Rightarrow\) \(\left[{}\begin{matrix}X-2=3\\X-2=-3\end{matrix}\right.\)\(\Rightarrow\)\(\left[{}\begin{matrix}X=3+2\\X=-3+2\end{matrix}\right.\)\(\Rightarrow\left[{}\begin{matrix}X=5\\X=-1\end{matrix}\right.\)
Vậy x=5 hoặc x= -1
