\(\left|x\right|-\left|-5,25\right|=\left|10,75\right|\)
\(\Rightarrow\left|x\right|-5,25=10,75\)
\(\Rightarrow\left|x\right|=10,75+5,25\)
\(\Rightarrow\left|x\right|=16\)
Vậy x = 4 hoặc x = -4.
tick mik nha
\(\left|x\right|-\left|-5,25\right|=\left|10,75\right|\)
\(\Rightarrow\left|x\right|-5,25=10,75\)
\(\Rightarrow\left|x\right|=10,75+5,25\)
\(\Rightarrow\left|x\right|=16\)
\(\Rightarrow\left[{}\begin{matrix}x=16\\x=-16\end{matrix}\right.\)
Vậy \(x\in\left\{16;-16\right\}.\)
Chúc bạn học tốt!
