(5cos + cosx) = sin(3x + 9)

Reorder the terms:
5cos + cosx = ins(9 + 3x)
5cos + cosx = (9 * ins + 3x * ins)
5cos + cosx = (9ins + 3insx)

Solving
5cos + cosx = 9ins + 3insx

Solving for variable 'c'.

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

Reorder the terms:
5cos + cosx + -9ins + -3insx = 9ins + -9ins + 3insx + -3insx

Combine like terms: 9ins + -9ins = 0
5cos + cosx + -9ins + -3insx = 0 + 3insx + -3insx
5cos + cosx + -9ins + -3insx = 3insx + -3insx

Combine like terms: 3insx + -3insx = 0
5cos + cosx + -9ins + -3insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(5co + cox + -9in + -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 '(5co + cox + -9in + -3inx)' equal to zero and attempt to solve: Simplifying 5co + cox + -9in + -3inx = 0 Solving 5co + cox + -9in + -3inx = 0 Move all terms containing c to the left, all other terms to the right. Add '9in' to each side of the equation. 5co + cox + -9in + 9in + -3inx = 0 + 9in Combine like terms: -9in + 9in = 0 5co + cox + 0 + -3inx = 0 + 9in 5co + cox + -3inx = 0 + 9in Remove the zero: 5co + cox + -3inx = 9in Add '3inx' to each side of the equation. 5co + cox + -3inx + 3inx = 9in + 3inx Combine like terms: -3inx + 3inx = 0 5co + cox + 0 = 9in + 3inx 5co + cox = 9in + 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.
