Question

Answer 1

`c, 203-5(2+x)=33`

`=> 5(2+x)=203-33`

`=> 5(2+x)=170`

`=>2+x=170:5`

`=>2+x=34`

`=>x=34-2`

`=>x=32`

`e,(x+1)^2=25`

`=>x+1=+-5`

\(\Rightarrow\left[{}\begin{matrix}x+1=5\\x+1=-5\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=4\\x=-6\end{matrix}\right.\)

`f,(x-2)^2=1`

`=>x-2=+-1`

\(\Rightarrow\left[{}\begin{matrix}x-2=1\\x-2=-1\end{matrix}\right.\)

\(\Rightarrow\left[{}\begin{matrix}x=3\\x=1\end{matrix}\right.\)

Answer 2

bạn tách ra `3->4` câu thôi ạ
