I am in 8 class and learning this but in my syllabus there is only linear equations in one variable that I can solve very easily so I am learning something new
Eq-(1) is multiplied by 4 and Eq-(2) is multiplied by 3, we get; 16x+12y=28........(3) 9x+12y=30..........(4) Now Eq-(4) is substracted from Eq-(3), we get; 7x = -2 x = -2/7 Put the value of x in eq-3, 12y = 28 - 16x = 28+32/7 = 228/7 y = 228/84
Thankuuu sir mai toh lockdown se lekr ab tk 10 ane tk mujhe yahi lg rha tha ki sabse bakwaas ch h jo mere palle hi nhi pdh rha mtlb mere se adha kaam ho jata lekin equation na niklti m preshan board ke exam se ab do din phle mujhe a gya

Right
Right
Haan
Specially in question without constant
Yes
dear sir hi sahi hai ‼️
This is not a trick but it's a descriminant method.😎
discriminant method is not also similar to this
Are woh descrimate nahi determinant/cramers rule/cramers method he
Woh wala alag he
It is determinant method
Discriminant is different thing
Formula?
@@Gaming75645 compare the equations with ax+by=c
Find a¹, a², b¹, b², c¹, c².
Multiply a¹ with b²,a² with b¹
Then you'll get D
Multiply c¹ with b²,c² with b¹
They you'll get Dx
Multiply a¹ with c²,a² with c¹
Then you'll get Dy
To find x divide Dx with D(Dx/D)
To find y divide Dy with D(Dy/D)
This is Cramer's rule
this is given in 10 standard as rule of cross multiplication
Gazab bhai I know this but wasnt renembering what it is but nice conceptual knowledge bro
Ya..Its Cramer's Rule
Yes our sir teach us in 9th std
Ye sab trick bolke hamko pagal baba rehe hai
sir 1 second already over you took 12 sec
i regret this
😂
It's a scam bro
Sir 00 mark milega😊😊😊😂😂
😂😂 Cramers rule pagal Bana diya...sir you are grate....😅
Bhai vo great hota hai 😂
It's called cross multiplication method. NCERT mein available hai bhai!!!
rationalised ho gaya, ab syllabus mai nahi hai
5x+7y=50----(1)
7x+5y=46----(2)
When we cross multiply,
X=250-322/25-49
X=3
But for y this is irrational fraction
Y=65/7 (after further solution)
actual answer is x=2 and y=6 so the video method is wrongg
Boards teachers after watching the video

Best method for solving this
Nice trick and explanation sir👍👍 uday'smathsclasses
Can we use this for boards 2024 ?
No cuz this is a direct method u can only do it in objective to save time
No
No, hamare Sir ne to btai thi ye trick , 2018 when I was in my 9th standard 😅❤
But thank you for reminding 😊❤
🤣🤣🤣🤣🤣🤣 ratne wale baccho, bawal trick nhi h bs sir ne direct kr diya multiply
Sir ji Mai abhi tenth me aur ye aapka video thoda helpful laga but ye trick ncert me Diya hai cross multiplication hai jii❤
its not working for all question
don t use in exam
thanks
It always works bro 💯
Maybe ur using it wrong 😅
It is deleted topic😅
Sir this trick is usefull for all questions
nhi bhai
Pta tha guru 10th me hi ,,,,,bhale hi aaplogo ko n bataya gya ho lekin apna guru bahut best educator the🏅🏅🏅🏅
It works 🎉
Yes
😂
Sir ye trick theory paper me likhe to chalega kya
No
Eq-(1) is multiplied by 4 and Eq-(2) is multiplied by 3, we get;
16x+12y=28........(3)
9x+12y=30..........(4)
Now Eq-(4) is substracted from Eq-(3), we get;
7x = -2
x = -2/7
Put the value of x in eq-3,
12y = 28 - 16x = 28+32/7 = 228/7
y = 228/84
Sir make video on 3 equation pkz
Methods are really good thanks sir 👍🏻
Thank you sir🙏 for give me a better method to solve
Your trick have a fun ☺️ short trick 😁
Thank u so much such a great 📷📸 aise hi video banate rahiye
Thank you sir 🎉❤
So nice of you😌
Sir can I use this method in board exam
Not accepted but you can use it for MCQs and 1mark questions
Yeah😥
Brilliant sir 👏
sir class x ka math compartment classes chahiye please don't forget me
This method is called cross-multiplication method, for cross-multiplication some formula should be used.
Are guru ji kaha the itne dino tak
Thanks sir for giving short trick to find any linear equations that help me very much in board exam❤
🥰
Sir exam mein ye method likh shkte kya?
It is useful for competitive exams only
Thank you sir🙏
Sir, if there is a change of sign in equation.
Please taught about that also.
Sir ya to cross multiplication method hai
this is cross multiplication method earlier in ncert
It's just Cross multiplication And u made it a trick 😁😁😁😁
Thankuuu sir mai toh lockdown se lekr ab tk 10 ane tk mujhe yahi lg rha tha ki sabse bakwaas ch h jo mere palle hi nhi pdh rha mtlb mere se adha kaam ho jata lekin equation na niklti m preshan board ke exam se ab do din phle mujhe a gya

Trick nahi h ye.. Method h ye cross multiplication of equation ka... Determinantsolving method kehte h ise
Thank you sir
Thank you Bhaiya forever
Sir Kya Trick Batayi H
Butt
Ye Cramer's Rule h😂😂
Aap ne ye vdo hum 10th me the tab uplode kyu nahi kiya 😅

Sir you are osm ❤
WHY IS RUclips RECOMMENDING THIS AFTER MY MATH EXAM. just why
Sir elemination method and substitution method are far more easier than this cross multiplication method !!!!
I guess this is called cramers rule
U are the best Sir thanks a million 🥰
Thanks to you too for appreciating🫶
