^{4}spanned by S.

## Homework Equations

S: {(2,9,-2,53), (-3,2,3,-2), (8,-3,-8,17), (0,-3,0,15)}

I've attempted this using a matrix and row reducing it. I'm just not sure if there's another simpler way, as I keep on getting incorrect numbers in the matrix, when I try and put it in row-echelon format. Thanks in advance for any and all assistance.

See ya on the flipside,
