Question

Answer 1

\(\left|1,5-x\right|=0,25-0\)

\(\left|1,5-x\right|=0,25\)

\(\left[{}\begin{matrix}1,5-x=0,25\\1,5-x=-0.25\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=1,5-0,25\\x=1,5-\left(-0,25\right)\end{matrix}\right.\)

\(\left[{}\begin{matrix}x=1,25\\x=1,75\end{matrix}\right.\)

Vậy...

 

Answer 2

`0,25 - |1,5 - x| = 0`

`=>      |1,5 - x| = 0,25 - 0`

`=>      |1,5 - x| = 0,25`

`=>      1,5 - x = 0,25 hoặc 1,5 - x = -0,25`

`*TH1`

`1,5 - x = 0,25`

`=>    x = 1,5 - 0,25`

`=>     x = 1,25`

`*TH2` 

1,5 - x = -0,25`

`=>  x  = 1,5 + 0,25`

`=>  x  = 1,75`
