Answer:

[tex]x=4, y=-3[/tex]

Step-by-step explanation:

[tex]\left[\begin{array}{ccc}2x+4y=-4\\3x+5y=-3\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}6x+12y=-12\\6x+10y=-6\end{array}\right][/tex]

[tex]\begin{bmatrix}6x+12y=-12\\ -2y=6\end{bmatrix}[/tex]

[tex]\frac{-2y}{-2}=\frac{6}{-2}[/tex]

[tex]x=4,y=-3[/tex]

Hope this helps! Please mark brainliest!
