Simplifying 5x = cosx Solving 5x = cosx Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1cosx' to each side of the equation. -1cosx + 5x = cosx + -1cosx Combine like terms: cosx + -1cosx = 0 -1cosx + 5x = 0 Factor out the Greatest Common Factor (GCF), 'x'. x(-1cos + 5) = 0Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(-1cos + 5)' equal to zero and attempt to solve: Simplifying -1cos + 5 = 0 Reorder the terms: 5 + -1cos = 0 Solving 5 + -1cos = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1cos = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1cos = 0 + -5 -1cos = 0 + -5 Combine like terms: 0 + -5 = -5 -1cos = -5 Add 'cos' to each side of the equation. -1cos + cos = -5 + cos Combine like terms: -1cos + cos = 0 0 = -5 + cos Simplifying 0 = -5 + cos The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
