Have you lined them up yet?
OpenStudy (anonymous):
i dont know how 2
OpenStudy (anonymous):
You need to align them as -5x+3y=6
x- y=4
OpenStudy (anonymous):
Then, you need to multiply the bottom by 3 to be able to eliminate the y.

3x-3y=12
OpenStudy (anonymous):
-5x+3y=6
3x-3y=12
OpenStudy (anonymous):
After you've found what x equals, substitute it back in to find y.
OpenStudy (anonymous):
y=2
OpenStudy (anonymous):
y=-4

X=-9
so y should equal -5
OpenStudy (anonymous):
-5x+3y=6
3x-3y=12
----------
-2x=18
x=-9
OpenStudy (anonymous):
whats the final answer?
OpenStudy (anonymous):
-9-y=4
+9 +9
------
y=13
OpenStudy (anonymous):
x=-9
y=13

Just fill in the values
OpenStudy (anonymous):
The question asks for an ordered pair, none, or infinite. In this case, it was an ordered pair so you answer (-9,13)
