Solving
xF = 3cosx

Solving for variable 'x'.

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

Add '-3cosx' to each side of the equation.
-3cosx + xF = 3cosx + -3cosx

Combine like terms: 3cosx + -3cosx = 0
-3cosx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-3cos + F) = 0

Subproblem 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 = 0

Subproblem 2

Set the factor '(-3cos + F)' equal to zero and attempt to solve: Simplifying -3cos + F = 0 Reorder the terms: F + -3cos = 0 Solving F + -3cos = 0 Move all terms containing x to the left, all other terms to the right. Add '-1F' to each side of the equation. F + -1F + -3cos = 0 + -1F Combine like terms: F + -1F = 0 0 + -3cos = 0 + -1F -3cos = 0 + -1F Remove the zero: -3cos = -1F Add '3cos' to each side of the equation. -3cos + 3cos = -1F + 3cos Combine like terms: -3cos + 3cos = 0 0 = -1F + 3cos Simplifying 0 = -1F + 3cos The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
