Simplifying sin(5x) = sin(7x) Remove parenthesis around (5x) ins * 5x = sin(7x) Reorder the terms for easier multiplication: 5ins * x = sin(7x) Multiply ins * x 5insx = sin(7x) Remove parenthesis around (7x) 5insx = ins * 7x Reorder the terms for easier multiplication: 5insx = 7ins * x Multiply ins * x 5insx = 7insx Solving 5insx = 7insx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '-7insx' to each side of the equation. 5insx + -7insx = 7insx + -7insx Combine like terms: 5insx + -7insx = -2insx -2insx = 7insx + -7insx Combine like terms: 7insx + -7insx = 0 -2insx = 0 Divide each side by '-2'. insx = 0 Simplifying insx = 0 The solution to this equation could not be determined.
