linear algebra, thankss

(3) Consider the linear system 2.37] $2 + 3233 = a 3:151 -I 1'2 5593 = b 5$1 5332 + 213:3 = C Determine the relations between a, b and e such that the system is i. inconsistent; ii. consistent, and then solve the system. 1 1 3 2 (13) Consider vectors v1 = 2 , 1:2 2 1 , v3 = 3 and 114 = 4 in R3. 3 4 2 6 Show that 111,112,113, 114 are linearly dependent, and {111,112} spans the same subspace of R3 as span{t:1, 1,12,1331114}
