You can maybe try talk to a teacher or something to help you Maybe try get an app or something that can also explain it to you more easily? Maybe try search for another video?
Base on what I've learned this isn't correct or maybe it's just different numbers that u used than what I used. Cause I used 2 and 3 to get the coefficients to be equal numerically
Because they got the value of y in the first equation which is 3 so instead of writing y with the first equation they multiplied by 3 aka the value of y
Around 3000 BCE, the Sumerians developed a numerical system based on the sexagesimal system (base 60), which is still in use for measuring time (seconds, minutes, and degrees in a circle) today. They also made strides in geometry, algebra, and arithmetic.
i dont really comment on math videos but thank youuu this was really helpful :>
maths exam tmr thx for help
Same 😂🤸🏾♀️
how mych did u get
Yep
Same
For the subtraction method, does it matter which equation you subtract from which?
you explained this so well i fully understood all of it tysm
Totally confused....where is ×2 coming from??
Thank u dis helps mi out alot
U have really made it easy for me
Very good explanation thank u
nice video im writing my final exams in few months
Where did the 2x come from? In problem 2
Your question is confusing, elaborate.
Why multiple by 3 and when did 9 come from
the multipled by three so that it would match up with the other y which is 3y so it could cancel out. SOrry if it isn't well explained
i am confused
Omg
life is confusing
Than your too slow or you hadn't tried this at school yet no offence
11X===77
X=7
14----6==8
21++2==23
Y'all aren't indians thats why you confused 😂
3:22 how did you get the x=7 bc u only said you divided thr 11x and 77 by 11 and then you skip to x=7
he got 7 because he divided the 77 by 11 leaving x behind, so x=7
My question is also this
Thanks a lot. I do have pro with these topic but now am cool.
Well explained 👍😊
you dont know hom helpfull this videos is, thxx!!
Thank you so much ❤
I love this guy! ❤👍
when do you add and subtract 2 and 3 because you added in the first one and subtract in the second and didnt explain
I swear I don't know myself, I've watched so many videos and no one explains it and I ended up on this video tryna find an explanation
how do uk what to multiply by
This is very easy, thanks
I love this❤😊.little by little you will understand ❤
nice calculation
I learned a lot in this
Those markers are smooth damn
What made you multiply The second equation by 3 ?
It's so that we can cancel the y value in the joined equation so we can solve for x and find y later.. 3y and -3y cancel out
On the last problem, i got x as -47/11 and y as 63/11. When substituting into equation 1, it came out as 33 so im confused
You can maybe try talk to a teacher or something to help you
Maybe try get an app or something that can also explain it to you more easily?

@user-sm8to1ib4r it's been a year, I think we both know I've probably figured this out by now but thanks.

Where did you get 3 from?
21 by 63 is 3
Bro I did not understood even I practiced it for 10 timesss
Now I understood cuz of uu🙏🏻🙏🏻
Thanks 😊😊 for it
thank u so much i have a math exam tommorow😭
Why you multipley eqution 1 times 3
My goat
Still don't understand 😢😢
Excuse me why did you multiply by three
Thank you so much
Thank you very much i really understand the equation
I don’t understand 😢
Thank you
Base on what I've learned this isn't correct or maybe it's just different numbers that u used than what I used. Cause I used 2 and 3 to get the coefficients to be equal numerically
But dear the answers should come same, if it's different the n it's definitely wrong......
whaaaaaaat I have no idea whats going on here bro your method its very confuse based on what I know😞😞😥😥😥
Seconds equation by 3 how
I understand but not understand ion know how that works
thx this helps, nice vid
Why take 3 n 2 ????
Plz reply
To match the equation so that two values can cut each other
really helpful thanks
Thanks a lot🌞

Noice
👌
is it just me or i cant understand y i keep getting my x as 0.7 in my question!
Well defined and explained
2:20 group like terms
Taught well but I didn't get the concept
why do you times by 3? wthhhhhh
The median of the data 8kg.7kg.9kg.10kg.and 11kg please
9kg
How to know when to add or subtract equation
Bro what is this I’m so lost
Why are you multiplying by 3?
Am confused
Broiler ate the math book how does he know this
anybody that says i don not understand is right
X=7 and Y= -2
🤔
I don't' understand elimination
Why multipliying by 3
tht is what i want to know to.Why 3
To match the equations so that two values can cut each other
Because they got the value of y in the first equation which is 3 so instead of writing y with the first equation they multiplied by 3 aka the value of y
This help me but I don't understand 3× and 2×

Difficult way of expressing to leanners
😢
2x3 = 6 not 9
He has wrote 2 because he wants because he has multiplied equation 2 by 3
9X--3y==69
2X+3y==8
===
11X==77
X=7
14--6==8
21--(-2)==23
Y=-2
Y do I think these comments are sarcastic
real
Your way is complicating
Hi
This isn’t it at all净人一门
its bad explination
Nah your probably just too stupid no offence
Fake who taught these fake things
Ho
Thank you so much🎉
why multiply by 3
Bcoz we have to make the 2 eqns y same as 1 so it multiply by 3 so it will become 3y and then both get cancelled
