No, it's not b. Subtracting 3x from both sides is fine there, that combines all the x terms to one side.

8. deezgurls

So then it would be adding the 2? Because since it's the same equation and they did it right with 3x for combining the terms

9. DebbieG

No, adding the 2 on both sides is ok. See, one is moving the x terms to the right side and the constants to the left; the other is moving the x terms to the left and the constants to the right. Either is fine, just different approaches but both mathematically sound. There is, however, a different step that someone did that is NOT mathematically sound. :) Keep looking!

When aaron subtracted the 8 because he got -8

11. DebbieG

YOu mean when Aaron subtracted 6?? (When aaron subtracted 8 is not one of the options). That is the error, but it isn't because he got -8. On that side, he had -2-6 which is, indeed =-8 Why is it wrong that he subtracted 6?
