OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

^final answer

OpenStudy (anonymous):

thats wrong

OpenStudy (anonymous):

What did you get?

OpenStudy (anonymous):

i put that answer and it not leeting me go throw

OpenStudy (anonymous):

It's an ordered pair. Sorry!

OpenStudy (anonymous):

I reread the question.

OpenStudy (anonymous):

You should type (-9,13)

OpenStudy (anonymous):

That's what it is asking for, i believe

OpenStudy (anonymous):

i giv up

OpenStudy (anonymous):

An ordered pair is (x,y) That's how you write one.

OpenStudy (anonymous):

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)

OpenStudy (anonymous):

I hope I could help! Sorry, if i couldn't.
