Hi, I dont quite grasp what is happening here. How did the (x1,x2,x3) just disappear?
#What happens with the (x1, x2, x3)?
golden cloud
dawn anchorBOT
brisk osprey
because its equivalent to putting it on another vector space as x1 x2 x3
if u multiply the matrix with just numbers * the other matrix you will get the same equation

But how do we end up with 5x1 + 2x2 -x3 etc. ? Where did the numbers come from?

It’s because of the 1/6 in front. We essentially did x_1 - (1/6)x_1 which is (5/6)x_1
