\textbf{Given:}

\mathsf{2x-y=-1}

\mathsf{3x-y=7}

\textbf{To find:}

\textsf{Solution of the given simultaneous equations}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{2x-y=-1}----(1)

\mathsf{3x-y=7}-----(2)

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

\mathsf{-x=-8}

\implies\boxed{\mathsf{x=8}}

\mathsf{Put\;x=8\;in\;(1)}

\mathsf{2(8)-y=-1}

\mathsf{16-y=-1}

\mathsf{y=1+16}

\implies\boxed{\mathsf{y=17}}

\therefore\textbf{Solution is x=8 and y=17}

\textbf{Find more:}

4x - 3y = 16; 6x + 5y = 62.​
