Plug them in... -4=x -5=y

-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)

-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)

Therefore the ordered pair IS NOT the solution.

Hope this helps :)

<h2>Answer:</h2>

There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

$2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\$

Now we will solve for y using what we got for x.

$2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0$

Solution:

A: $(0, 3)$
