**Hello!**

I have just started studying linear algebra and I got the following question:

We have:

Expres u as a linear combination of the vectors v and w.

Expres u as a linear combination of the vectors v and w.

**This is my attempt;**

(By definition a vector is called a linear combination of [tex]v_{1}, v_{2},... v_{k}[/tex] if it can be expressed in form [tex]c_{1}v_{1}, c_{2}v_{2},... c_{k}v_{k}[/tex] )

So we get: [tex]c_{1} (4,3,2,1) + c_{2} (1,1,1,1) [/tex]

Is this right? Is this all we were required to show?

Thanks you.
