A.

6x + 4y = 2








B.

4x – 6y = 2








C.

6x – 4y = –2








D.

6x – 4y = 2

Answer 1

\[8-4x+4y=2x+6\]

Answer 2

that's not one of the choices though..

Answer 3

\[6x-4y=-2\]

Answer 4

the last one

Answer 5

oh! thanks :)

Answer 6

anytime :)

Answer 7

wait, wouldn't it be C since the -2?

Answer 8

8 - 4 (x - y) = 2x + 6 -- distribute through the parenthesis
8 - 4x + 4y = 2x + 6 -- subtract 8
-4x + 4y = 2x + 6 - 8 -- subtract 2x
-4x - 2x + 4y = 6 - 8 -- combine like terms
-6x + 4y = -2 -- multiply by -1 to make x positive
6x - 4y = 2

Answer 9

thank you both
