Simplifying F(x) = cos((7x) + -2) Multiply F * x xF = cos((7x) + -2) Reorder the terms: xF = cos(-2 + (7x)) xF = (-2 * cos + (7x) * cos) xF = (-2cos + 7cosx) Solving xF = -2cos + 7cosx Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7cosx' to each side of the equation. -7cosx + xF = -2cos + 7cosx + -7cosx Combine like terms: 7cosx + -7cosx = 0 -7cosx + xF = -2cos + 0 -7cosx + xF = -2cos Reorder the terms: 2cos + -7cosx + xF = -2cos + 2cos Combine like terms: -2cos + 2cos = 0 2cos + -7cosx + xF = 0 The solution to this equation could not be determined.
