Subproblem 2
Set the factor '(s + 3S)' equal to zero and attempt to solve:

Simplifying
s + 3S = 0

Reorder the terms:
3S + s = 0

Solving
3S + s = 0

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

Add '-3S' to each side of the equation.
3S + -3S + s = 0 + -3S

Combine like terms: 3S + -3S = 0
0 + s = 0 + -3S
s = 0 + -3S
Remove the zero:
s = -3S

Add '-1s' to each side of the equation.
s + -1s = -3S + -1s

Combine like terms: s + -1s = 0
0 = -3S + -1s

Simplifying
0 = -3S + -1s

The solution to this equation could not be determined.
