Combine like terms: 2insx + -2insx = 0
60cos + 2cosx + 0 = 30ins + -2insx
60cos + 2cosx = 30ins + -2insx

Reorder the terms:
60cos + 2cosx + -30ins + 2insx = 30ins + -30ins + -2insx + 2insx

Combine like terms: 30ins + -30ins = 0
60cos + 2cosx + -30ins + 2insx = 0 + -2insx + 2insx
60cos + 2cosx + -30ins + 2insx = -2insx + 2insx

Combine like terms: -2insx + 2insx = 0
60cos + 2cosx + -30ins + 2insx = 0

Factor out the Greatest Common Factor (GCF), '2s'.
2s(30co + cox + -15in + inx) = 0

Ignore the factor 2.

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 '(30co + cox + -15in + inx)' equal to zero and attempt to solve: Simplifying 30co + cox + -15in + inx = 0 Solving 30co + cox + -15in + inx = 0 Move all terms containing c to the left, all other terms to the right. Add '15in' to each side of the equation. 30co + cox + -15in + 15in + inx = 0 + 15in Combine like terms: -15in + 15in = 0 30co + cox + 0 + inx = 0 + 15in 30co + cox + inx = 0 + 15in Remove the zero: 30co + cox + inx = 15in Add '-1inx' to each side of the equation. 30co + cox + inx + -1inx = 15in + -1inx Combine like terms: inx + -1inx = 0 30co + cox + 0 = 15in + -1inx 30co + cox = 15in + -1inx 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.
