\(2x^2-xy+3x-2x=5\)
\(2x^2-xy+1x=5\)
\(xy=2x^2-x-5\)
\(x\left(2x-y+1\right)=5\)
\(\Rightarrow x=5\)
\(\Rightarrow y=\frac{2x^2+x+5}{x}\Rightarrow\frac{2.25+5+5}{5}=12\)
\(\Rightarrow y=12\)
Vậy \(\left(x;y\right)=\left(5;12\right)\)

\(\Rightarrow y=\frac{2x^2+x-5}{x}\Rightarrow\frac{2.25+5-5}{5}=10\)
\(\Rightarrow y=10\)
Vậy \(\left(x;y\right)=\left(5;10\right)\)
