- This video will cover how to solve linear simultaneous equations using substitution and elimination methods. This is relevant to O levels Maths 4024 and Igcse Maths 0580.
I’m an ex maths olevels student (didn’t opt for add maths) I can’t even begin to explain my emotions right now, its been around a week since maths p2 and life seems like heaven without maths. Oh what I would do to never open a maths book ever again. Maths made me cry straight from grade 1 to
11th, may allah save everyone from the wrath of vectors, mensuration kinematics and so many more horrendous topics. Finally my condolences to those who have opted for maths in Alevels, may allah guide you!
(Please remember me in your prayers as my paper 2 went terrible)
have my majors next year 😥
- Reality is hard to face 😂
Result?

thank you so much for all your lectures helped me thru my mids may allah give u barkat in ur risk and shower his blessing upon u ameen
Ameen
@@maheenharoonmukaty6851 hi maheen! 😅 lol
love u sir , u r the best maths teacher i have ever had .
20:41 he first found the value of y then again y in substitution, but it was supposed to be X's value.
Yes
Oh okayy,I was confused in this
Also the 116-95 = 58
Also wouldn't the answer be x=37 as the divided by two would multiply and phir subtraction, there wouldn't be any fraction left
@@UnitedGamingDaYTum? No? 💀💀💀
sir i would really request for you to not cut the videos from between. it gets really confusing as youre solving an equation and suddenly its just gone. (example 14:55 ) other than that thank you for making maths easier
💀
Same with me
there was probably some kind of lag in between his class in which maybe he wasnt audible so the editor cut that part
Idk why but after watch zainematics I have literally fallen in love with maths 😭
😇
@@ZAINEMATICS THATS WHY THE MOTTO IS ''FOR THE LOVE OF MATHS''.
It looks so easy with your methods, I am able to understand maths after so much time 😂
Happy to hear that!
@@ZAINEMATICSsyllabus ma simultaneous linear equation likha ha same cheeze ha?
@@sgjutt7964 yeah ig
It was really helpful. Thank u Sir Zain.
Is there any prob in the editing of the video bcz sometimes it show different qs and then move another qs pls let me know
There is
You have eye sight problem😅
@@mirzareshail4052 ooh thank you for letting me know I will get it check and thank you once again
@@emanyousaf494too much sarcasm 😂
Yes he basically skips the part which is repetitive
Sir in the last question you have written y instead of x
thankyou sir this was very helpful 🙏🏻
cha gai ho bhai cha gai ho
Thankyou sir ,🙏🏻💫
thanks so much!!! all clear now :)
Sir mai abhi recent November sitting mei maths derai hu. Or aap bohot achay ho sir!! Apki har video dekhne k time mei sacchi dil se dua nikalrai hai but I still wanna know that will this form of maths be ok for edexcel version because as far I know that you have taught the Cambridge version. Sure nai hu mai.
result kia aya
luvly teacher
Maza aa gaya 🤟💥💯
Sir I have a question, after making term X or Y same we got 4 equations. Two with no change and and 2 after making term same. So for finding the other value of x or y can we put the other value in any of these four equations?
Thanks sir your every lecture is very informative for me
level hi alag apka
Thank you so much sir this video was really helpful
Most welcome bachay😊
@@ZAINEMATICS😅😅 mujhe aap ke video hamesha paper se aik din pehle kholne hote hain😅😅

very helpful
we love you!!!! :)
there were 2 possible outcomes for the value ofy in the 14:55 part question and the circumstances and conditions were not guided
gooooooooooood
Thank you this is so helpful!!!!!
Yes we can put. But the recommended way is to put in one of the final equations
Sir for making sign different, can we multiply term by -1??
Is this part of algebra?
Yes
where are these gonna used in real life wth is this system:/
You are a angel
Helpful
love u sir
is this video enough for this topic?
Absolutely but its js for concept he has posted the other vid for practice
I js realized it was 2y ago😂
Thankyou thankyou thankyou sir !
How to apply for the January course?(for cies may june 24)
Sir last main it was y ki value ya x , because y ki value pehly nh niklgai? 21upon2?
Sir what about the questions that tell you from which method to solve. There’s a question in my book which must be solved from substitution method but the question is telling me to solve it with elimination method.
then u must follow the question's instructions
@understandingmath1
Oxford syllabus
D1, D2, D3 Math solutions are availabe in my channel, just click, watch and subscribe.
Why did we make X value same in elimination...before u were not changing signs and just making Y Value same and cutting them...whats the logic behind when to make X same ?
_ in short at 7:21 why not make y same ??
_ or is that substitution??
We need to see two main things while doing elimination process:
1. You need to make any one variable value same. It can be x or y that's totally up to you to decide so I was doing one example with each of them. Again it's for you to decide which one are you making same.
2. The terms that we just made same in first step must have opposite +/- signs so that when we add both equations these terms get canceled.
But in q1 u didn't change the signs
sign change wasn't needed there
what about paper 2 sir because the questions are quite confusing
sir does this topic comes in paper2?
Rarely but it comes in joint question some times
@@laiqahafeez4517 haha yeah just for paper two...memorize the entire notes beacuse sometimes even paper 1 topics question come as joint.....for ex: probability comes in paper 2 with the statistics questions
Sir selling price cost price wale chp ane me kitna time hai.plzzzz jaldi upload krdey
Can we have an answer in decimals if we solve an equation by the elimination or by subsitution method?
💀
Yes
@@mairakhan885 thanks
Thank you so much 💜💜💜💜
army?
@@laiqahafeez4517 💀
Will it matter if I choose to work on x or y
no
isnt it 32- - 65? at 11:20
no, it was supposed to add but bcs the signes changed at the second equation it is 32 plus minus 65 which is equal to minus 33
Sir equation ko same karnay kayliay 2 say multiply kerna zaroori hai
Sir plz reply..
Nahi bro equation same karne ke lie kisi se bhi multiply jar sakte
Having extra knowledge
♥️
Aoa. Sir will simultaneous equations only come in p1 or p2 also
Both
bbbhbhbh@@Amuhaymin06
can anyone tell me how 7y come on 17:18
-4y is moves to left and sign change then it was add with 3y and become 7y
Done
I just dont get why he changes the signs of lower equation?
It was needed because opposite signs of x are cancelled. The signs were same, thats why instead of adding the equations, we subtracted them, which lead to changing the signs.

Is it necessary to change the signs in elimination method.
No
👍
thankooooo

Ur video has error which is making it more confusing 🙄
