Question

Answer 1

/x-1/4/=0,5+1/2

/x-1/4/=1

TH1: x-1/4=1

x=1+1/4=5/4

TH2: x+1/4=-1

x=-1+1/4

x=-3/4

 

Answer 2

\(\left|x-\dfrac{1}{4}\right|=1\)

\(\left\{{}\begin{matrix}x-\dfrac{1}{4}=1\\x-\dfrac{1}{4}=-1\end{matrix}\right.\)

\(\left\{{}\begin{matrix}x=\dfrac{5}{4}\\x=\dfrac{-3}{4}\end{matrix}\right.\)
