    I have been watching all your explanations for a year now and still have to watch because I have many Maths in my major, and your channel is the world's most helpful resource for Math. Keep up the good work and thank you!

    you go a bit too fast but in the end, everything you explain is very clear. (take this from a person who is extremely slow at math)

    in my opinion, this lesson was the hardest in Algebra 2 in high school for me in 2009. I absolutely hated it as it was hard to follow along, and one simple mistake along the way would screw up the entire answer. I was very good in Algebra 2 and managed to get A's on ALMOST every quiz...except this one. I barely passed the quiz on this, but thankfully it didn't hurt my grade too much. Still, I have not-so-fond memories of this lesson. After watching your video, it makes just a bit more sense, but it's still as headache-inducing as what I once remembered it being!

    Jesus, I am 2 assignments away from my final. I have been STRUGGLING on math this whole damn time. I am taking this class online. My book I bought to "teach" me has been nothing but dog shit. I cannot believe how long it has taken me to turn to Freaking UA-cam to learn math. I am so grateful for this video. I'll be coming here more often now. The moment he showed how to distribute, that was my "AHH ha!" moment. My book assumes you know this shit, so I was confused this whole time. So hyped right now.

    Would the numerator for the solution not be x - 17? Because when we're subtracting right before it, we're doing (-5) - 12 which equals (-17)?
