Answer 6

Answer 7

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

Answer 8

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

Answer 9

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!

Answer 10

When aaron subtracted the 8 because he got -8

Answer 11

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?
