@oldrin.bataku help on this one??

Answer 2

\[
\ \ \ 2x-5y=19\\
\ \ \ 4x+10y=-22\\
\text{Multiply the first by 2.}\\
\ \ \ 4x-10y=38\\
\text{Combine the first and second.}\\
\ \ \ 8x=16\\
\ \ \ x=2\\
\text{Find }y\text{ after solving for }x.\\
\ \ \ 4(2)+10y=-22\\
\ \ \ 10y=-22-8=-30\\
\ \ \ y=-3
\]
