Let a=⟨1,3,1⟩ and b=⟨2,−1,−4⟩ Show that there are scalars s and t so thatsa+tb=⟨4,−16,−20⟩You might want to sketch the vectors to get some intuition.Where do I begin and end with this problem?Thank you in advance for your help.

You may disregard the part that says "part 0/2" you are not missing anything. Please just follow the instructions over it.  thank you!

You are doing some calculations about a solar panel on the roof of a house as shown in the image below. To help you with your work, you have determined the components for two vectors a=<-10,0,6> and vector b=<0,4,0> on the solar panel. Additionally, the current position of the sun means that the sunshine is coming at a direction given by the unit vector s=<1/3,2/3,-2/3> *I hope you answer all question and wrote detail

If you could show steps not just answers please
