hint: start by adding the two equations together.

OpenStudy (anonymous):

Ok

Vocaloid (vocaloid):

so, what do you get after you add everything together? ...

OpenStudy (anonymous):

And then u find x then u substitute it for y

Vocaloid (vocaloid):

no, that's not what I meant

Vocaloid (vocaloid):

add the two equations down on paper, then tell me what equation you get after you add the two equations together

OpenStudy (anonymous):

I got x=3 and y=-1

OpenStudy (anonymous):

Is that right

Vocaloid (vocaloid):

yup, good job

Vocaloid (vocaloid):

remember, you can always check your answer by plugging in x = 3 and y = -1 back into both equations

Thanks :)
