x=-5

Answer 2

|x-5|=10 
x - 5 = +-10 
xét 2 th 
th1
x-5 = 10 
x= 15 
th2
x-5 = -10 
x = -5  

Answer 3

`|x-5|=10`

`@TH1:x-5=10=>x=10+5=15`

`@TH2:x-5=-10=>x=-10+5=-5`

Vậy `x=15` hoặc `x=-5`

Answer 4

|x – 5| = 10

\(=>\left[{}\begin{matrix}x-5=10\\x-5=-10\end{matrix}\right.=>\left[{}\begin{matrix}x=15\\x=-5\end{matrix}\right.\)
