This is so helpful. Next time I go to the grocery store to buy shit ill use linear systems with 3 variables to figure out if my tomato soup is boneless

This is so much easier than the way my teacher taught it to me. I would take 20 minutes or so to just answer one question. Organizing the equations with letters makes it better to understand. Thank you for the help!
Yeah I'm still so confused.

Guys, don't be despondent. This problem has many methods to solve, but the two I use are used in calculus and are very effective. .Firstly, find the equation in A and B, which produces D, if you like. .Then find the equation in A and C, which produces E. .Then find the solution to one of the variables using D and E. .Use solution gained from D and E and substitute it in either D or E, which will give you the solution to the second variable. Now, that you have found the two variables, the rest is easy. .Substitute them into the original equation(A or B), which will produce the solution for the last variable.

I love how you tried to combine art with math. Its like combining war and peace.
YOU ROCK. I’m a tutor, I needed a refresher, your method did the trick!
Love this video! You explain it much more simply than my math teacher.

Great Work, you're enthusiasm matched with the simplicity of you're explanations helped me understand it with ease. Thank you so much :)
A great video that shows students how to keep track of the information inside these types of questions. That skill must be mastered to confidently solve systems. I request you add the ordered pair solution of (x, y, z) as the final form; a point in space.
i love your energy in this long boring solution, as u said its a tip of the iceberg
you are my actual saviour, love you man
This is actually my first time commenting on a KZread video Thank you very much for explaining
EXTREMELY helpful. Thank you !
YES! this video was perfect. So easy to follow!
Thank you so much! I appreciate your help!!
very nice illustration. Thanks a lot...
So helpful... Teacher went over this shit way too fast. Could understand anything she said.
you are the great lecture cause you made me think like we are leaning together .thumbs up
can you substitute numbers you get at the beginning into any other equation to find x or y?
Thanks so much, 'twas excellent. Now I'm gonna watch it again to make sure I'm good on the subject
Thanks Richard...May God bless you.
thank you so much this helped me immensely with my year 9 home work
Great! Thanks, very easy to follow!
👍👍 thank you sir your way of explanation is great
How do you know which number to multiply each equation at the beginning?

Great teacher and actor!!!
first time seeing your video but it's great helped a lot and couldn't help think that I'm watching blues clues for math
What an amazing teacher
Great sir! Now I understand thanks.
Best out there!!Awesome!! Thank you!!
How do you now which equations to sub in X, Y, and Z after you found one of the variables?

are there any rules about which equation is added or subtracted from which? like, do you have to add or subtract all equations from the same first one? a-b and a-c?
@creampuff966
7 жыл бұрын
You can use any combination of equations and you'll still get the same answer. You can use a-c and a-b, or b-c and a-b. Whatever works for you :)
Loved it!
omg thank you so much. Bless your heart for making this video!

what if coefficients of variables are also in the form of a b and c like a1x+b1y+c1z ,a2x+3b2y+3c2z and a3x+b3x+c3x
thank you !!

A smart board I guess in my school teachers use it to teach and sometimes use the black borad
Atleast there are 3 equations and 3 variables... we have 1 equation and 2 variables in number theory (along with another constraint like all solutions are integers)
WOULD B and C work as well instead of A and C?
how do you know if a system of linear equation has no solutions, infinite solutions, or one solutions?
Whats that thing u r using to write?
Awesome video. But also, are you familiar with someone by the name Nicholas Cage?

Can I just row echelon it?
What about if it's nonlinear?
Thanx dude
good!!
is it just me or does your plug in for B not calculate i get - 5(3)-2(7)+4(-8) = -31 not 25?? But A & C work out ok (confused!!)

Hello, Can someone please help me with this equation?? I always get lost in the way... e + fn + g = 9 2e + fn + g = 20 9e + fn + g = 37 I can't do it :(
@diorrat..0
3 жыл бұрын
I think- (I’m not sure) (9e + fn + g) - (2e + fn + g) = 37 - 20 (9e - 2e) + (fn - fn) + (g - g) = 17 7e = 17 e = 17/7 Substitute e. 17/7 + fn + g = 9 Multiply 7 on both sides 17 + fn + g = 63 fn + g = 63 - 7 = 56 g = 56 - fn Substitute again into any equation you like. Check your work

instead of using letters like D,E,F,G, I suggest you to use A1,B1,C1 instead. A lot more letters is more confusing
