for the following set of vectors, determine if they are linearly dependent or independent. FOr the cases which are linearly dependent, write one of the vectors as a linear combo of the others.

1) (1,1,2,-1),(2,-2,1,3),(8,-4,7,7)

2) (1,1,2,6),(3,1,q,0),(5,1,2,-6) (How does the answer depend on q (belonging to R)?)
