Cramer's rule aside, your handwriting is what I want to learn.

Yes brother

I used to do Adjugate Matrix/Cofactor Matrix and Transformation Matrix and mix them up to get something that takes longer to do than using the normal way to solve these without matrixes. But then you show me this that is super intuitive and super simple

Great video James! I've been exploring a more efficient way to solve for 3 variables via Cramer's Rule: After finding 2 of the unknowns, plug them back into one of the original equations. Solve for the third variable. Plug all three variables into the equations to check your work. I hope someone finds this "quick and dirty" method helpful!

Why did I never learn this in school. a lot easier in some cases.

Couldn’t explain it better. So awesome thanks!!!!

super useful and uber concise, thank you!

Hyy sir I am from india nd prepare for iit It's great method to solve Thanks lot to give clear technique.... 🥰

Awesome simple, step by step explanation. Plugging in the values x, y, z and the equations are proven!! (1/2, -2/3, 5/6). Revisiting my love for mathematics. Thank you, Sir

Thanks for making this video. It really helped me out.

Beyond helpful. This is by far the most simple and efficient way to solve systems of equations. Thank you!

Just wanted to say your handwriting is the neatest most beautiful print i have ever seen

Wow easy to understand !!!! Thank you!

Wow this is straightforward... Thank you

This fast solution is what I'm looking for.

bro thanks so much my professor makes everything so complicated

Wow this is an easy method of linear system than equation by elimination prone to errors. Btw tnx man you did great just keep uploading math videos so very helpful

This video is the only one I've found that makes it crystal clear what the algorithm is to solve these. This is good, because I'm taking a very significant math test next week for an endorsement for middle school math. 5 hours long. OOOOoooooofffffff. Not really looking forward to this!

Thank so much! This really helped! God bless!

How do you solve x-2y + z=-1 3x - 2y -2z=7 x + 3y-2z = 5 Using crammers rule

Only -15 will be touched by negative?

That handwriting is my handwriting dream

Basically he is using Cramer's rule and Sarrus's rule. The method he is using seems like a neat alternative for converting the coefficient matrix augmented with the constant matrix and converting it to row echelon or Reduced row echelon form.

❤

done

your method was actually really harder than what it actually is... using a finger while looking at the row (up+down) and seeing the rest of the values is way easier 100%

Can this method be used for a 4x4 matrix?

@hsmathsolutions

Yup! You can do any size system. Just follow the same procedure, but extend it for 4x4 (4 variables). The problem is that finding determinants for larger square matrices can be quite a challenge (lots of busy numeric computations). It's often better left for a computer system!

@@hsmathsolutions Thank you. It would be great and really helpful to know how you'd solve a 4x4 with Cramer's since I couldn't find any example with your method.

The determinant is 27; and y=-11 so I doubt the answers

Hope no text in screen

Hey babe I like your handwriting aaaw😛😍

Its so hard

bruh why didnt my teacher tech my the diagonal method

Your answers are wrong man when I prove they don't give me the original answers from the equation why...??

Ow sorry I left a negative sign

This is SARRUS rule.😅

this method does not work on all linear equation sorry Bro.

Cramer's Rule is ubiquitous. It works for every linear system. This video covers linear systems that have single ordered triplet solutions. Cramer's Rule also covers systems with no solution and infinite solutions, but not in this video.

why tf you find the determinant this way? its stupid
