1. The problem statement, all variables and given/known data for some reason I am having real trouble trying to solve this system. 2. Relevant equations 3. The attempt at a solution a=(10,11,4) v1=(2,1,4) v2=(-1,-2,1) v3=(3,3,-1) the qstn does a belong to the span (v1,v2,v3)? so I do gauss elim but I keep running into dead ends can someone please show just the steps to start i.e. R1=R2 +R3 because every time I have tried I can't get the bottom row to have ENOUGH 0'S!! Thanks.
