tìm các số nguyên x {|x|+2017} x {504|x|-2016} <0

Answer 1

/x/=1/3

Answer 2

\(\left|x\right|=\left|-\frac{1}{3}\right|\)

\(\left|x\right|=\frac{1}{3}\)

\(\Rightarrow\text{ }x\in\left\{-\frac{1}{3}\text{ ; }\frac{1}{3}\right\}\)

Answer 3

\(\left|x\right|=\left|-\frac{1}{3}\right|\)

\(\left|x\right|=\frac{1}{3}\)

\(\Rightarrow\orbr{\begin{cases}x=-\frac{1}{3}\\x=\frac{1}{3}\end{cases}}\)

\(\Rightarrow\text{ }x\in\left\{-\frac{1}{3}\text{ ; }3\right\}\)

Answer 4

|x|=|-1/3|

x=1/3

vậy x=1/3
