Step-by-step explanation:
7j - 4j + 6 < -2 + 3j
3j + 6 < -2 + 3j
6 < -2
this is wrong for any value of j, as 6 is definitely not smaller than -2.
so, the set of possible values for j is the empty set.
if you did not make any mistake or typo in the problem description, this is the only possible answer.
