The 2-step Equations videos explain how to solve 2-step equations including negative solutions, but not negative coefficients. In addition, the exercises that accompany the video do not have any negative coefficients (or negative solutions from what I can see although there is subtraction which indicates that there are "negative" constants).

There are separate exercises for 1-step equations (add/subtract) with negatives and 1-step equations (multiply/divide) with negatives. I believe it would be very helpful if there were also a set of exercises for 2-step equations with negative coefficients and solutions.

What are you looking for help with? Or is this just a request to change Khan?

I contacted the help desk about this issue and they recommended that I post the request on this forum. I think that this would be a very helpful change because there ought to be a place where there exists practice for 2-step equations and the focus is negative numbers, in my opinion. It seemed like something that had been overlooked. However, if there is a pedagogical reason for not having that exercise, I would certainly be interested in hearing (and debating it) here.
