Subproblem 1

Set the factor 'inx' equal to zero and attempt to solve: Simplifying inx = 0 Solving inx = 0 Move all terms containing i to the left, all other terms to the right. Simplifying inx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(3s + S)' equal to zero and attempt to solve: Simplifying 3s + S = 0 Reorder the terms: S + 3s = 0 Solving S + 3s = 0 Move all terms containing i to the left, all other terms to the right. Add '-1S' to each side of the equation. S + -1S + 3s = 0 + -1S Combine like terms: S + -1S = 0 0 + 3s = 0 + -1S 3s = 0 + -1S Remove the zero: 3s = -1S Add '-3s' to each side of the equation. 3s + -3s = -1S + -3s Combine like terms: 3s + -3s = 0 0 = -1S + -3s Simplifying 0 = -1S + -3s The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
