If (2, -1, 2, 1) is a linear combination of the three given vectors, then there should exist
such that

or equivalently, there should exist a solution to the system

Right away we get
, so the system reduces to

Notice that the first equation is the sum of the latter two. The third equation gives us

so that in the second equation,

which in turn gives

and hence the (2, -1, 2, 1) is a linear combination of the given vectors, with

Answer:
b- x=5
Step-by-step explanation:
14-5=8 so your answer would be b
Yes it is going to be easier
