Question

tìm số nguyên x : |x|-1=5

Answer 1

|x|-1=5

|x|=5+1

|x|=6

vậy x\(\in\){6;-6}

Answer 2

=> \(\left[x\right]=6\)

=> \(\left[{}\begin{matrix}x=6\\x=-6\end{matrix}\right.\)

Answer 3

\(|x|-1=5\)

⇔\(|x|=6\)

⇔\(\left[{}\begin{matrix}x=6\\x=-6\end{matrix}\right.\)

Answer 4

\(\Rightarrow\left|x\right|=6\Rightarrow\left[{}\begin{matrix}x=6\\x=-6\end{matrix}\right.\) Vậy...

Answer 5

\(|x|=6\) 

\(\Rightarrow x=6\) hoặc -6

vậy...

Answer 6

Ta có: \(\left|x\right|-1=5\)

\(\Leftrightarrow\left|x\right|=5+1=6\)

hay \(x\in\left\{6;-6\right\}\)

Vậy: \(x\in\left\{6;-6\right\}\)
