    This kingdom has an awful lot of convenient problems.

    Sal seriously, I dont know how its possible for u to have another talent, but your drawings are so well defined and show such understanding of shape and proportions!
    Please do a series on drawing or something where u illustrate more. U might be the Indian reincarnation of da Vinci :3

    Great way of explaining how there arises an infinite number of solutions to a system of equations. Thank you Khan.

    You should give an example where the system is consistent and gives 1 solution but that solution is nonsensical or forbidden by a further constraint such as a > 0 and b > 0.

    Nice example. Kept my attention.

    I have done loads of matrices but I just watch for the funny story about the troll and the bird.

    I still don't understand why we have to multiply by -3 what happens if I have other numbers? My book says to multiply by -2 but doesn't give a reason. What should I do?

    Wouldn't negative 2a go to the left of the b axis?

    I can't believe it, Mitt Rommny called me himself, but he got my name wrong! He called me Russel. Yes, for two unknowns you need two different equation with the same variables. Let n be number of unknowns, then to solve for each variable, you need to setup n number of equations.

    Well if he becomes president we might care about him, but since he called me I have also had calls from Clint Estwood, and Ann Romney, among others. I am not, in any way endorsing Romney, nor am I endorsing Obama. Regarding this video, I might mention that just because we may have the same number of unique equations as unknowns, we are not guaranteed a unique solution to each unknown. An example might be a line passing through a sin wave.
