Thank you so much! Quick question: when I did the last question, I got the right answer for x but I did it by taking (-3) and subtracting (-7) from it. The answer is still 4 haha so at least that's right. I did the same for y and z and still got the right answers. So my question is: can you do it both ways or did I just get lucky with this one?
I've covered many of these GED math topics in videos my channel already.

Also, please note that I've covered many topics in my GED math practice test and quiz videos, and in my live streams too, which don't have full videos on (yet). So just because I don't have a link to a video on a topic here, that doesn't mean I've never talked about it on this channel before. There's a good chance that I've discussed it in one of my other videos.
