\textbf{Given:}

\textsf{Equations are}

\mathsf{x+5y=165^\circ}----------(1)

\mathsf{2x+4y=180^\circ}--------(2)

\textbf{To find:}

\textsf{x and y}

\textbf{Solution:}

\textsf{We solve the given equations by elimination method}

\mathsf{(1){\times}2}-(2)\implies

\mathsf{2x+10y=330^\circ}

\mathsf{2x+4y=180^\circ}

\mathsf{6y=150^\circ}

\mathsf{y=\dfrac{150^\circ}{6}}

\implies\boxed{\mathsf{y=25^\circ}}

\mathsf{(1)\implies}

\mathsf{x+5(25^\circ)=165^\circ}

\mathsf{x+125^\circ=165^\circ}

\mathsf{x=165^\circ-125^\circ}

\implies\boxed{\mathsf{x=40^\circ}}

\textbf{Answer:}

\mathsf{x=40^\circ}

\mathsf{y=25^\circ}

\textbf{Find more:}

8x-19y=2550

7x-16y=2550
