10cos + cosx + 0 = 20ins + -3insx
10cos + cosx = 20ins + -3insx

Reorder the terms:
10cos + cosx + -20ins + 3insx = 20ins + -20ins + -3insx + 3insx

Combine like terms: 20ins + -20ins = 0
10cos + cosx + -20ins + 3insx = 0 + -3insx + 3insx
10cos + cosx + -20ins + 3insx = -3insx + 3insx

Combine like terms: -3insx + 3insx = 0
10cos + cosx + -20ins + 3insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(10co + cox + -20in + 3inx) = 0

Subproblem 1

Set the factor 's' equal to zero and attempt to solve: Simplifying s = 0 Solving s = 0 Move all terms containing c to the left, all other terms to the right. Add '-1s' to each side of the equation. s + -1s = 0 + -1s Remove the zero: 0 = -1s Simplifying 0 = -1s 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 '(10co + cox + -20in + 3inx)' equal to zero and attempt to solve: Simplifying 10co + cox + -20in + 3inx = 0 Solving 10co + cox + -20in + 3inx = 0 Move all terms containing c to the left, all other terms to the right. Add '20in' to each side of the equation. 10co + cox + -20in + 20in + 3inx = 0 + 20in Combine like terms: -20in + 20in = 0 10co + cox + 0 + 3inx = 0 + 20in 10co + cox + 3inx = 0 + 20in Remove the zero: 10co + cox + 3inx = 20in Add '-3inx' to each side of the equation. 10co + cox + 3inx + -3inx = 20in + -3inx Combine like terms: 3inx + -3inx = 0 10co + cox + 0 = 20in + -3inx 10co + cox = 20in + -3inx 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.
