In this video I demonstrate how to find the basis for the solution space to a homogeneous linear system. The dimension of the solution space is also determined.

im not even from your university but you explained it so well in 1/10 of the time that my lecturer took to explain, thank

Bruh this is so helpful. When you actually try to understand this, its totally easy. Thank you

can we say that basis are the solution that satisfies system by writing its parametric equation ? (what i mean basis generates parametrical solution which satisfies the system)

But how can it even have a basis when it should not be able to form a basis since it fails to be linearly dependent (it forms a nontrivial solution)?

Newbie here, why is rref all zeros on Row 2 and 3? shouldn't all rref have diagonal 1's and rest are 0s?

How would you do this for a non homogeneous system?

so in other words you could say that the dimension of a solution space of a system of linear equations (SLE) is definend by n (Number of variables) - rank (of the SLE) = number of free Variables..

Why do R2 and R3 columns be of zeros in rref?
