/ x-7/ - (-15)^ 0 = /-6/
=> x- 7 - 1 = 6
=> x - 8 = 6
=> x= 14
h nhé
\(\left|x-7\right|-\left(-15\right)^0=\left|-6\right|\)
\(\left|x-7\right|-\left(-15\right)^0=6\)
\(\left|x-7\right|=6+\left(-15\right)^0\)
\(\left|x-7\right|=6+1\)
\(\left|x-7\right|=7=\left|7\right|=\left|-7\right|\)
+) \(x-7=7\) +) \(x-7=-7\)
\(x=7+7\) \(x=\left(-7\right)+7\)
\(x=14\) \(x=0\)
Vậy x=14 hoặc x=0
|x - 7| - (-15)0 = |-6|
|x - 7| - 1 = 6
|x - 7| = 7
\(\Rightarrow\orbr{\begin{cases}x-7=7\\x-7=-7\end{cases}\Rightarrow\orbr{\begin{cases}x=14\\x=0\end{cases}}}\)
