Subproblem 2
Set the factor '(13S + -7s)' equal to zero and attempt to solve:

Simplifying
13S + -7s = 0

Solving
13S + -7s = 0

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

Add '-13S' to each side of the equation.
13S + -13S + -7s = 0 + -13S

Combine like terms: 13S + -13S = 0
0 + -7s = 0 + -13S
-7s = 0 + -13S
Remove the zero:
-7s = -13S

Add '7s' to each side of the equation.
-7s + 7s = -13S + 7s

Combine like terms: -7s + 7s = 0
0 = -13S + 7s
