Answer 2

@cram @aum

Answer 3

We want x and so eliminate y.
Multiply second equation by 2 and add it to the first equation. What do you get?

Answer 4

wot m8

Answer 5

3x + y = 6
multiply throughout by 2.
what do you get?

Answer 6

6x+y=12

Answer 7

6x+2y=12?

Answer 8

Yes. Now add this to the first equation.
6x + 2y = 12
x - 2y = 2
Add

Answer 9

x+6x=7x?

Answer 10

am i doing that right

Answer 11

6x + 2y = 12
x - 2y = 2
---------------
7x 0 = 14
----------------

7x = 14
divide both sides by 7
x = 2

Answer 12

We are adding like terms above.

6x + x = 7x
2y + (-2y) = 0
12 + 2 = 14

Answer 13

well i knew how to do that part at least. thanks for setting it up for me. i understand it now

Answer 14

you are welcome.
