How to do Vectors Cambridge Question (1 Viewer)

[hmim]

Hi,

I'm stuck on this question. I tried equating the equations in a and b and then trying to show it equals to equation c but it doesn't work.

Would someone be able to show their working for this question if they arrive at the correct answer, please

Any help would be greatly appreciated, thanks!

Maybe try expanding and adding together the equations in a and b
