Question

| x- 1/3 | = 5/6

tìm x

Answer 1

Answer 2

| x- 1/3 | = 5/6

Ta có:

TH1: x-1/3=5/6

x= 5/6+1/3

x= 7/6

TH2: x-1/3=-5/6

x= -5/6+1/3

x= -1/2

Vậy x=7/6, -1/2

Answer 3

\(\left|x-\dfrac{1}{3}\right|=\dfrac{5}{6}\)

Có \(\left[{}\begin{matrix}x-\dfrac{1}{3}=\dfrac{5}{6}\\x-\dfrac{1}{3}=\dfrac{-5}{6}\end{matrix}\right.\Rightarrow\left[{}\begin{matrix}x=\dfrac{7}{6}\\x=\dfrac{-1}{2}\end{matrix}\right.\)

\(\Rightarrow x=\left\{\dfrac{7}{6};\dfrac{-1}{2}\right\}\)
