Is this not how everyone did it? This is the method i learnt in school...wow that makes me feel smart even tho i did probably the worst in my class!

[@tecmath]

As you'll see from other comments... a lot of people do it a much longer way. It's exhausting.

this is how I was taught as well haha

@@tecmath now i need to know what this longer way is lmao!

[@AbdullahWaqar454]

@@CactusFragz well, you take the 5 in the denominator over to the other side, and multiply that by 3 that makes 15. The take the 3 to the other side and subtract that from 15. That leaves us with 4x=12, take the 4 to the right and divide it by 12. 12÷4=3.

Exactly how we were taught in the US we when I was in school. What nonsense did you learn down under?

[@divahc1]

None! I went to high school from '73 to '78 and this is EXACTLY how we did it. I don't know what he's talking about. Only difference is we did one step at a time, which is normal practice when learning something new. I teach maths now, and I still each it this way. We were taught that whatever you do to one side do the same to the other. So, to clear the division from the LHS, multiply both sides by 5, for example. Then, we'd write down that step. Once we had done that we'd do the next step. Writing out each step is good practice for learners as it keeps them focussed, gives them a written record of their working so they can find errors in their working if their final answer is incorrect. As teachers, marking exams, it gives us the opportunity to award marks for correct working, even if a calculation is slightly out. I don't know what he's talking about in this video, when he says 'lines and lines of messy working'. 🤷🏼‍♀️

[@timclifford8809]

So this is the same, and I expect only, _way_ of working out the answer, just without rewriting the equation after each step. The reason they get you to do that in school is so if you make a mistake at one point they can see you still had the right idea and might be able to give you credit for that, as opposed to just having nothing but the wrong answer and no proof that you understand what to do, you just made a mistake.

Right? I don't get it either.

[@LarimaBeyondBorders]

It’s been over 20 years since my first algebra class but if I remember correctly, we would put parentheses around (4x+3/5) and multiple both sides by 5 to eliminate the fraction. This ends up being : 4x+3=3(5). -> 4x+3=15. -> 4x=12 -> x=3

I have been subscribed for a long while. I teach adult education, IOW people who have not yet gotten a high school equivalency and the majority of them stalled on math. I think it is more effective to offer people a variety of approaches to learning, so I refer them to your videos to supplement class work. The value in your videos is in cutting the time. The HiSET test is timed, and test takers have to be able to work problems efficiently and timely. I also enjoy watching your videos for my own improvment.
