Solve linear equations in two variables in just 10sec #maths #shorts #khantrickster

[videoworld]

I am solve my question with the help of you. Love you sir❤

[Wahajfans-lgwd]

M 10 me hu 10 class 2024-25 attendance here 😅❤❤

[dineshrathod]

it's not working for all question so don't use in examination ❤❤❤❤

[monishprasath.v]

sir 1 second already over you took 12 sec
i regret this

[bulletsgaming]

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)

[sanskar]

This is not a trick but it's a descriminant method.😎

[dgsgsgsfh]

It's called cross multiplication method. NCERT mein available hai bhai!!!

Eq-(1) is multiplied by 4 and Eq-(2) is multiplied by 3, we get;




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

Nice trick and explanation sir👍👍 uday'smathsclasses

[uttampushkar]

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

[VinayakTupkari-jewn]

😂😂 Cramers rule pagal Bana diya...sir you are grate....😅

[saylishirsath]

Sir ye trick theory paper me likhe to chalega kya

[rahulkoli]

No, hamare Sir ne to btai thi ye trick, 2018 when I was in my 9th standard 😅❤
But thank you for reminding 😊❤

[venonricinov]

cramer method..
x = Dx/D
y = Dy/D

Dx determinan by removing x
Dy determinan by removing y
D determinan by removing const

simple

[rajwardhan]

Sir ji Mai abhi tenth me aur ye aapka video thoda helpful laga but ye trick ncert me Diya hai cross multiplication hai jii❤

[Sachinshroff]

its not working for all question
don t use in exam
thanks

[nationalisms]

Sir this trick is usefull for all questions

[hardikahuja]

Thanks sir for giving short trick to find any linear equations that help me very much in board exam❤

[HD_GAMERZ]

This method is called determinant method
