Simplifying sen(4x) = sen(-2x) Remove parenthesis around (4x) ens * 4x = sen(-2x) Reorder the terms for easier multiplication: 4ens * x = sen(-2x) Multiply ens * x 4ensx = sen(-2x) Remove parenthesis around (-2x) 4ensx = ens * -2x Reorder the terms for easier multiplication: 4ensx = -2ens * x Multiply ens * x 4ensx = -2ensx Solving 4ensx = -2ensx Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '2ensx' to each side of the equation. 4ensx + 2ensx = -2ensx + 2ensx Combine like terms: 4ensx + 2ensx = 6ensx 6ensx = -2ensx + 2ensx Combine like terms: -2ensx + 2ensx = 0 6ensx = 0 Divide each side by '6'. ensx = 0 Simplifying ensx = 0 The solution to this equation could not be determined.
