You said that you tried twice and had 2 different answers. Show us what you got and how you arrived at your result.

i cant type it out but i will tell u my approach..

I tried forming the augmented matrix for part 1 and trying to reduce it to row echelon form hence solving for a b c...

for part 2 i tried the same procedure as part 1 but this time checking whether if you multiply the scalar by the vecotr it will give you the same solution as what was given...

part 3 rammed my brain....

thanks
