4cos + 5cosx = (-18ins + 8insx)

Solving
4cos + 5cosx = -18ins + 8insx

Solving for variable 'c'.

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

Reorder the terms:
4cos + 5cosx + 18ins + -8insx = -18ins + 18ins + 8insx + -8insx

Combine like terms: -18ins + 18ins = 0
4cos + 5cosx + 18ins + -8insx = 0 + 8insx + -8insx
4cos + 5cosx + 18ins + -8insx = 8insx + -8insx

Combine like terms: 8insx + -8insx = 0
4cos + 5cosx + 18ins + -8insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(4co + 5cox + 18in + -8inx) = 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 '(4co + 5cox + 18in + -8inx)' equal to zero and attempt to solve: Simplifying 4co + 5cox + 18in + -8inx = 0 Solving 4co + 5cox + 18in + -8inx = 0 Move all terms containing c to the left, all other terms to the right. Add '-18in' to each side of the equation. 4co + 5cox + 18in + -18in + -8inx = 0 + -18in Combine like terms: 18in + -18in = 0 4co + 5cox + 0 + -8inx = 0 + -18in 4co + 5cox + -8inx = 0 + -18in Remove the zero: 4co + 5cox + -8inx = -18in Add '8inx' to each side of the equation. 4co + 5cox + -8inx + 8inx = -18in + 8inx Combine like terms: -8inx + 8inx = 0 4co + 5cox + 0 = -18in + 8inx 4co + 5cox = -18in + 8inx 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.
