        B is the matrix          ⌈  3      1  −3⌉         ∣  1      2a   1  ∣         ⌊  0       2    a ⌋   i.find the value of a for which B is       singular             ii.determine whether or not                 ⌈x ⌉         ⌈ −3.5⌉     B        ∣y  ∣  =    ∣      5.5∣  has the                 ⌊ z  ⌋        ⌊       5  ⌋  solution for each of the value of obtai  ned in (i) above

 determinant ((3,1,(−3)),(1,(2a),1),(0,2,a))  =3(2a^2 −2)−1(a+6)  =6a^2 −6−a−6  ∣B∣=0  6a^2 −a−12=0  a=((1±(√(1−4(6)(−12))))/(12))=((1±17)/(12))  a=(3/2),−(4/3)
