xF = -3 * 2cos * x

Multiply -3 * 2
xF = -6cos * x

Multiply cos * x
xF = -6cosx

Solving
xF = -6cosx

Solving for variable 'x'.

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

Add '6cosx' to each side of the equation.
6cosx + xF = -6cosx + 6cosx

Combine like terms: -6cosx + 6cosx = 0
6cosx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(6cos + 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 '(6cos + F)' equal to zero and attempt to solve: Simplifying 6cos + F = 0 Reorder the terms: F + 6cos = 0 Solving F + 6cos = 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 + 6cos = 0 + -1F Combine like terms: F + -1F = 0 0 + 6cos = 0 + -1F 6cos = 0 + -1F Remove the zero: 6cos = -1F Add '-6cos' to each side of the equation. 6cos + -6cos = -1F + -6cos Combine like terms: 6cos + -6cos = 0 0 = -1F + -6cos Simplifying 0 = -1F + -6cos The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
