Đáp án:x=1 hoặc x=-2/3
Giải thích các bước giải:
5/6-|1/6-x|=0
<=>|1/6-x|=5/6-0=5/6
<=>1/6-x=5/6 hoặc 1/6-x=-5/6
<=>x=-2/3 hoặc x=1
vậy x=1 hoặc x=-2/3
chúc bạn học tốt.
$\frac{5}{6}$ - ║$\frac{1}{6}$ -x ║=0
⇒ |$\frac{1}{6}$ -x| = $\frac{5}{6}$
⇒ \(\left[ \begin{array}{l}\frac{1}{6} -x=\frac{5}{6}\\{1}{6} -x=\frac{-5}{6}\end{array} \right.\)
⇒ \(\left[ \begin{array}{l}x=\frac{-2}{3}\\x=1\end{array} \right.\)
Vậy x ∈ { $\frac{2}{3}$ ; 1}
