    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
