Answer:

[tex][-9, -6][/tex]

Step-by-step explanation:

{−5x + 8y = −3

{3x - 5y = 3

⅗[−5x + 8y = −3]

{−3x + 4⅘y = −1⅘ >> New Equation

{3x - 5y = 3

______________

[tex]\frac{-\frac{1}{5}y}{\frac{1}{5}} = \frac{2\frac{1}{5}}{\frac{1}{5}}[/tex]

[tex]y = -6[/tex][Plug this back into both equations above to get the x-coordinate of −9]; [tex]-9 = x[/tex]

I am joyous to assist you anytime.
