Answer:−

\sf \: x+2y=4; 2x+y=5x+2y=4;2x+y=5

{\huge{\mathfrak{\underbrace{\purple{Given:-}}}}}

Given:−

\begin{gathered}\star \: \sf \: x+2y=4........ \fbox{ equation \: 1}\\\star \: \sf 2x+y=5.........\fbox{ equation \:2}\\\end{gathered}

⋆x+2y=4........

equation 1

⋆2x+y=5.........

equation 2

{\huge{\mathfrak{\underbrace{\purple{Solution:-}}}}}

Solution:−

\begin{gathered}\sf \: 1st \: we \: have \: to \: multiply \: equation \: 2 \\ \tt by \: 2\end{gathered}

\begin{gathered}\tt \therefore \: 2(2x + y = 5) \\ \implies \tt \: 4x + 2y = 10...... \fbox{equation \: 3} \\ \\ \tt \: now \: subtract \: equation \: 1 \: and \: 3.\end{gathered}

∴2(2x+y=5)

⟹4x+2y=10......
