      Guys, i actually got the following which still work:
      z = -4 ; y = 8 ; x = 1
      all are variables which fit in the equation. Strange that the teacher did't show that there areother solutions to this...?

    Mr. McLogan,
    I passed my college placement exam because of your videos. I am a non-traditional student who lost nearly all mathematical knowledge after high school. Thank you so much for uploading all of these great videos. They have been a tremendous help. I also passed my first college-level math exam with a 90 the other day.

    I like how he doesn’t say unnecessary complicated stuff that we don’t need to know at all. He just says the steps and makes it easy to understand.

    • @wreckim
      @wreckim ปีที่แล้ว +2

      You make a good point. That's what this video is for. Just remember that there are other Majors where all that complicated stuff is certainly going to be needed.

    Absolute lifesaver. we are reviewing this in algebra 2 just for now, and i remembered how to do a regular 2 system, but forgot how to do a 3 system. i have so many after school activites and one of them cuts into my 7th period(math) which effectively cuts my learning. thank goodness this guy exists because i would be completely lost withought him

    When you multiplied equation A and B how did you come up with -5 and 2?

    • @brianmclogan
      @brianmclogan  7 ปีที่แล้ว +13

      Those are the scalars that allow me when multiplied to obtain the same coefficients for y so that y can be eliminated when I combine the equations

    • @Brobecreative35
      @Brobecreative35 6 ปีที่แล้ว +4

      Betty Echavarria oh because basically when he did A he was multiplying a negative by negative giving him a positive, so to cancel out y he need B to be negative and positive 2 was a good solution for that

  • @tristanfoss7469
    @tristanfoss7469 3 ปีที่แล้ว +2

    In fairness to teachers, no matter how you do or describe these types of equations, they always take forever and have a lot of variables that can accidentally be screwed up. In my class, no one liked this method because even if you can understand how to do it, it still takes forever. If you're clever, you can usually come up with usable shortcuts to math, but you always have to figure out X, Y, and Z the hard way.
