2x + 3y= 2 multiply this equation by 2= 4x + 6y = 4

4x-2y = -28

4x + 6y = 4

-4x -2y = -28

8y = 32

y = 4

2x + 3(4) = 2

2x + 12 = 2

2x + 2-12

2x = -10

x = -5

solution = (-5,4)

**Kate**, Wednesday, February 16, 2011 at 11:21amyou're on the right track but when you tried to subtract the 2 eq you only subtracted the first term, but left the others' signs the same.

It should look like this:

4x+6y=4

-4x+2y=28 now add the two eq together and redo the work you did before. if you have more questions just ask!

**Joella**, Wednesday, February 16, 2011 at 11:47amwhen I wrote the -4x -2y = 28

I forgot to put the next step which was -4x + 2y = 28

but isn't the rest of my steps the same still because when I subtracted those they became 8y = 32 and the rest Thanks for responding-I'm not sure if this isn't right still-I think the answer is correct minus the one step I forgot to write

**Joella**, Wednesday, February 16, 2011 at 11:56amI think I see where you mistook what I wrote-I'm doing the elimination method and subtracting the equations so the new equations were

4x + 6y = 4 after I multiplied first equation by 2

minus 4x -2y = -28 and so the 4x becomes -, the -2y becomes positive and the -28 becomes positive, correct

Thank you

**Kate**, Wednesday, February 16, 2011 at 12:29pmYou're right. I'm sorry. When I saw the missed step, I stopped looking at the rest of the work. You are correct.
