Simplifying 4x + -4y = Cos(x + y) 4x + -4y = (x * osC + y * osC) 4x + -4y = (osxC + osyC) Solving 4x + -4y = osxC + osyC Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1osxC' to each side of the equation. 4x + -1osxC + -4y = osxC + -1osxC + osyC Reorder the terms: -1osxC + 4x + -4y = osxC + -1osxC + osyC Combine like terms: osxC + -1osxC = 0 -1osxC + 4x + -4y = 0 + osyC -1osxC + 4x + -4y = osyC Add '4y' to each side of the equation. -1osxC + 4x + -4y + 4y = osyC + 4y Combine like terms: -4y + 4y = 0 -1osxC + 4x + 0 = osyC + 4y -1osxC + 4x = osyC + 4y Reorder the terms: -1osxC + -1osyC + 4x + -4y = osyC + 4y + -1osyC + -4y Reorder the terms: -1osxC + -1osyC + 4x + -4y = osyC + -1osyC + 4y + -4y Combine like terms: osyC + -1osyC = 0 -1osxC + -1osyC + 4x + -4y = 0 + 4y + -4y -1osxC + -1osyC + 4x + -4y = 4y + -4y Combine like terms: 4y + -4y = 0 -1osxC + -1osyC + 4x + -4y = 0 The solution to this equation could not be determined.
