How to solve linear combinations of vectors

WebA linear combination of these vectors is any expression of the form where the coefficients k 1, k 2 ,…, k r are scalars. Example 1: The vector v = (−7, −6) is a linear combination of the vectors v1 = (−2, 3) and v2 = (1, 4), since v = 2 v1 − 3 v2. The zero vector is also a linear combination of v1 and v2, since 0 = 0 v1 + 0 v2.
