Answer 2

\(x-2x+3=x-1\)

\(\Rightarrow-x+3=x-1\)

\(\Rightarrow-x-x=-1-3\)

\(\Rightarrow-2x=-4\)

\(\Rightarrow x=2\)

Answer 3

Ta có :

\(x-2x+3=x-1\)

\(\Leftrightarrow\)\(x-2x-x=1-3\)

\(\Leftrightarrow\)\(-2x=-2\)

\(\Leftrightarrow\)\(x=1\)

Vậy \(x=1\)

Answer 4

Ta có :

\(x-2x+3=x-1\)

\(\Leftrightarrow\)\(x-2x-x=-1-3\)

\(\Leftrightarrow\)\(-2x=-4\)
