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.
