Question

\(\left|x\right|-2,2=1,3\)

Answer 1

|\(x\)| - 2,2 = 1,3

|\(x\)| = 1,3  + 2,2

|\(x\)| = 3,5

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

Vậy \(x\in\) {-3,5; 3,5} 

Answer 2

\(\left|x\right|-2,2=1,3\)

\(\left|x\right|=1,3+2,2\)

\(\left|x\right|=3,5\)

\(x=-3,5\); \(x=3,5\)
