x - y = -3 x + 3y = 5

OpenStudy (anonymous):

Check the question again? :) Do you have any options? :)

OpenStudy (anonymous):

No, it's fill in the blank.

ganeshie8 (ganeshie8):

multiply first equation wid 3

OpenStudy (anonymous):

Okay :)

OpenStudy (anonymous):

Like 3x - 3y = -9?

ganeshie8 (ganeshie8):

yes ! now add both the equations together

ganeshie8 (ganeshie8):

3x - 3y = -9 x + 3y = 5 ------------ ?

OpenStudy (anonymous):

Oh, I think I get it now, to cancel them out! So, 3x^2 = -4?

ganeshie8 (ganeshie8):

close, but you need to add 3x to x

ganeshie8 (ganeshie8):

you wrongly multiplied there...

OpenStudy (anonymous):

4x?

ganeshie8 (ganeshie8):

yes

ganeshie8 (ganeshie8):

3x - 3y = -9 x + 3y = 5 ------------ 4x = -4 x = ?

OpenStudy (anonymous):

ok, so 4x = -4 and then I divide, so......x = -1?

ganeshie8 (ganeshie8):

perfect !

OpenStudy (anonymous):

Ok, Great! Thanks for helping me understand it!:)
