Consider an n-dimensional vector space (V, R), that is, there are up to n eleme.ts of V that can form a subset that is linearly independent over R. Let s - {vi,..., v,} C V with 4 < r < n be such that S is linearly independent over R. Determine, if possible, if W = {v1 + v2, v3 – vs} is linearly independent over R.

Consider an n-dimensional vector space (V, R), that is, there are
up to n elemei.ts of V that can form a subset that is linearly independent over R. Let
S = {v1,..., v,} c V with 4 < r < n be such that S is linearly independent over R.
Determine, if possible, if
W = {v + v2, v3 – va}
is linearly independent over R.
Hint: Assume that the vectors in W are linearly dependent over R. Then show that this
assumption leads to a contradiction, proving that W is linearly independent over R.
