Smh to the people commenting "how do people find this hard?" I think the core audience of this channel is people who are mathematically inclined, forgetting that a lot of people, a lot of high schoolers, dont understand some fundamentals as well as other people. And this channel is here to help those people, not critique them. And to that, i say, how exciting

Well It also depends upon how seriously do you take studying. Like in India it is very rare that you can even survive without studying so they teach this to us in grade 6 and 7 (students are not even in highschool at that time) while in ur country it is quite simple to get a job without prior knowledge so studying is not a very serious topic for you. Also you guys focus on memory more that analysis. Like think of it, you have the general form of quadratic eqn and quadratic formula on the tip of your tongue, but do you know how did we deduce that formula from the general eqn

@@lordscottish69 It’s only going to be hard for those who don’t know basic math fundamentals. Even then it takes a knowledge of Algebra and fractions to do this. 2 of the most hated topics in Mathematics.

I started by moving the (1 - x)/2 to the other side. A trick is that -(a - b) = (b - a). So I had 2x/(3pi) = (x - 1)/2, then I cross-multiplied.
@GlorifiedTruth
@GlorifiedTruth 6 дней назад
I moved the second fraction to the other side: 2x/3π = (x-1)/2 and cross multiplied. No better or worse than your way, but maybe a little quicker.

@Birol731 2 дня назад
My way of solution ▶ 2x/(3π) + (1-x)/2 = 0 by multiplying both sides with 2*3π, we get: 4x+ (1-x)*3π= 0 4x + 3π - 3πx=0 4x-3πx + 3π=0 x(4-3π) = - 3π x= -3π/(4-3π) ⇒ x= 3π/(3π-4)

no. consider this: lets say we have 3/(3-4) doing this normally, we get -3. but if we cancel the threes, we instead get 1/-3. hopefully my math doesnt suck after not having used it for three years
@kunpai9781
@kunpai9781 5 дней назад
​@@superubergoober yeah, you can't simplify things if they're added or subtracted (in this case of course, not in general). for example if it was 3pi/3pi * 4, then yeah you could simplify it and get 1/4. but not on this case since this is subtraction

It’s a standardized test used for college/university admissions, along with the ACT. Some schools are becoming test-optional, and some don’t even take it anymore. I think SAT used to stand for Scholastic Aptitude Test, but they stopped calling it that but kept the acronym as the name of the exam.
