Question

|x-1,5|=1/2

Answer 1

\(\left|x-1,5\right|=\dfrac{1}{2}\)
\(\left[{}\begin{matrix}x=2\\x=1\end{matrix}\right.\)

Answer 2

\(\left|x-1,5\right|=\dfrac{1}{2}\\ TH1\left|x-1,5\right|=x-1,5\\ =>x-1,5=0,5\\ =>x=0,5+1,5\\ =>x=2\\ TH2\left|x-1,5\right|=1,5-x\\ =>1,5-x=0,5=>x=1,5-0,5\\ =>x=1\)

Answer 3

`|x-1,5|=1/2`

`=>|x-1,5|=0,5`

`@ Th1`

`x-1,5=0,5`

`=>x=0,5+1,5`

`=>x= 2`

`@ TH2`

`x-1,5=-0,5`

`=>x=-0,5+1,5`

`=>x=1`

Answer 4

\(\left|x-1,5\right|=\dfrac{1}{2}\)

\(< =>\left[{}\begin{matrix}x-1,5=\dfrac{1}{2}\\x-1,5=-\dfrac{1}{2}\end{matrix}\right.< =>\left[{}\begin{matrix}x=\dfrac{1}{2}+1,5\\x=-\dfrac{1}{2}+1,5\end{matrix}\right.\)

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

Vậy ..........
