cosx + 12cos2x = 0 + -14cosx + 12cos2x
cosx + 12cos2x = -14cosx + 12cos2x

Add '-12cos2x' to each side of the equation.
cosx + 12cos2x + -12cos2x = -14cosx + 12cos2x + -12cos2x

Combine like terms: 12cos2x + -12cos2x = 0
cosx + 0 = -14cosx + 12cos2x + -12cos2x
cosx = -14cosx + 12cos2x + -12cos2x

Combine like terms: 12cos2x + -12cos2x = 0
cosx = -14cosx + 0
cosx = -14cosx

Solving
cosx = -14cosx
