Answer 1

\(x+\left(2x-8\right)=17\)

\(\Rightarrow\left(x+2x\right)-8=17\)

\(\Rightarrow3x=25\)

\(\Rightarrow x=\frac{25}{3}\)

Vậy \(x=\frac{25}{3}\)

Answer 2

x + ( 2x - 8) = 17

( x + 2x ) - 8 = 17

( x + 2x ) = 17 + 8

( x + 2x ) = 25

=> x = \(\frac{25}{3}\)

Answer 3

\(x+\left(2x-8\right)=17\)

\(x+2x-8=17\)

\(x+2x=17+8\)

\(3x=25\)

\(x=\frac{25}{3}\)
