    Couldn't you distribute the 4 making 4x+12=36 and then solve for x. The answer is still 6

    Why do you times it by 3 at the end of the equation? Are you supposed to always times them but didnt because the others were 1? Please explain

    • @jimbarnardmathtutorials6037
      @jimbarnardmathtutorials6037 5 дней назад

      Yes, I times by 3 because the numerator of that fraction was 3. You can think of times by 1 on the other fractions as their numerators were 1, but I didn't explicitly state that.

    Maybe a better way to teach this would be to graph this with an XY grid. Show, (2,1) then explain it's the midpoint of a line. Show point C and infer the other half of line. These are wonderful videos

      @@wakeful3282 oh yeah I forgot ap math was the beginner level. Since we don't use terms like that here it all gets a bit confusing. Here linear algebra is a course all engineers, physisists and mathematicians have to take. It would be after you finish your first course in mathematics on a university level (Mathematical analysis of one variable) and calculators were not allowed during those exams. Calculators are usually only allowed when the important part of the exam isn't being able to do math, it's being able to understand the equations and which situation they might be used in. Like thermal-fluid sciences.
