Consider the system
[[-6,-3,9],[6,3-3a,-18-3b]]
a. Given that
b!=-3
, for which value of the parameter
ainR
does the system have no solutions?
a=
b. This system has a unique solution for all except one value of
ainR
. What is this value of
a
?
a=
c. For which values of
a,binR
does this system has infinitely many solutions? Enter the values
a
and
b
separated by commas and in the specified order:
a
followed by
b
.
a,b=
