## Homework Statement

Find a basis for the subspace S of vectors (A+B, A-B+2C, B, C) in R4

What is the dimension of S?

## The Attempt at a Solution

Do I just plug in varying values for A B and C to create four vectors, and see if they are linearly independent? If they are then I've found a basis?
