\(-2x-\left(x-17\right)=34-\left(-x+25\right)\)
\(\Leftrightarrow-2x-x+17=34+x-25\)
\(\Leftrightarrow-3x+17=x+9\)
\(\Leftrightarrow4x=8\)
\(\Leftrightarrow x=2\)
\(-2x-\left(x-17\right)=34-\left(-x+25\right)\)
\(\Rightarrow-2x-x+17=34+x-25\)
\(\Rightarrow-3x+17=34-25+x\)
\(\Rightarrow-3x+17=9+x\)
\(\Rightarrow17-9=x+3x\)
\(\Rightarrow8=4x\)
\(\Rightarrow x=2\)
Vậy \(x=2\)
Ta có : \(-2x-\left(x-17\right)=34-\left(-x+25\right)\)
\(\Rightarrow-2x-x+17=34+x-25\)
\(\Rightarrow-3x-x=9-17\)
\(\Rightarrow-4x=-8\)
\(\Rightarrow x=2\)
Vậy x = 2
