Let a =1 -3 2-2 5 -13 -4 -8and b =b1b2b3determine if the equation ax = b is consistent for all possible b1, b2, b3. if the equation is notconsistent for all possible b1, b2, b3, give a description of the set of all b for which the equation isconsistent (i. e., a condition which must be satisfied by b1, b2, b3). what can you use this systemfor? a) equation is consistent for all b1, b2, b3 satisfying 2b1 + b2 = 0.b) equation is consistent for all b1, b2, b3 satisfying -3b1 + b3 = 0.c) equation is consistent for all possible b1, b2, b3.d) equation is consistent for all b1, b2, b3 satisfying 7b1 + 5b2 + b3 = 0.
