Consistent and Inconsistent Systems

Missed the previous lesson?

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Excellent teacher.  Other teachers could learn from him.

[rkh]

the video quality is so much better than older videos!

[ronymacwan]

Midsem paper of linear algebra tomorrow! Thanks.

[kesav]

HOW DOES HE WRITE SO NEATLY WITH A CURSOR??? BUT THANK YOU SOOO MUCH FOR YOUR HELP!!

[KBineetPrasadPatro]

Sir, I need about three unknown variables .

[Phenxious]

you can also just look at the x of both linear systems, if they haven't the same slope, you know that the system is consistent

[josephsimpunga]

you are my favorite guys, I wish I can know how get that clean and clear platform, I can pay for the info!

Thanks!

[saicharanjogu]

super very helpfull may be khan acdemy can be no 1

[sophia]

The first 34 seconds gave me my answer lol thanks so much 👌👌

[lalabla]

U don't need the chart right like u could just see if the slopes are the same or not

[theadel]

This way of figuring out whether two equation are consistent or not is inefficient(Time wasting). The best way is to see whether they have the same slope then the y-intercept.

[nirmalyadavnk]

what about when x, y and z is given???

[VSAA]

Thank you so much u made my doubts clear

[sriharitheerthagiri]

Thank you soo much sir!
Your work is remarkable!
Continue your work on mathematics and help students like me forever!
Once again thankyou very much for your help 💐

[juliand]

I only get confused when it is just letters and it tells me to tell if it is consistent equivalent or inconsistent.

[inpaulwetrust]

I did the slope form and I got y=-1/2x+6.5 which doesnt match the graph :/

[djstrobe]

Aaaahh I need to find universal sets GRRRR 

[divyajha]

Jb marne lgoge tb lagega give me another chance to live one more life
