hello people
i was wondering if anyone could help me with this question:
For what values of a and b does the system
ax +bz = 2
ax +ay +4z = 4
ay + 2z = b
have: (i) no solution
(ii) a unique solution
(iii) a one-parameter solution
(iv) a two-parameter solution?
this is what i did, i wrote it in a matrix form and i did gussian elimination, and across the diagonal i got a, a, and 1
i multiplied the digits on he main diagonal and i got a^2, i made that equal to 0... then i made this post
(basically I'm just doing random things with the numbers and I'm so stuck i don't know what to do! )
any tips would be really appreciated
cheers in advance!
