Subproblem 2
Set the factor '(1 + -3j)' equal to zero and attempt to solve:

Simplifying
1 + -3j = 0

Solving
1 + -3j = 0

Move all terms containing j to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -3j = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -3j = 0 + -1
-3j = 0 + -1

Combine like terms: 0 + -1 = -1
-3j = -1

Divide each side by '-3'.
j = 0.3333333333

Simplifying
j = 0.3333333333
Solution
j = {0, 0.3333333333}
