Simplifying rx + 2ry + kx + 2ky = 0 Reorder the terms: kx + 2ky + rx + 2ry = 0 Solving kx + 2ky + rx + 2ry = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1rx' to each side of the equation. kx + 2ky + rx + -1rx + 2ry = 0 + -1rx Combine like terms: rx + -1rx = 0 kx + 2ky + 0 + 2ry = 0 + -1rx kx + 2ky + 2ry = 0 + -1rx Remove the zero: kx + 2ky + 2ry = -1rx Add '-2ry' to each side of the equation. kx + 2ky + 2ry + -2ry = -1rx + -2ry Combine like terms: 2ry + -2ry = 0 kx + 2ky + 0 = -1rx + -2ry kx + 2ky = -1rx + -2ry Reorder the terms: kx + 2ky + rx + 2ry = -1rx + rx + -2ry + 2ry Combine like terms: -1rx + rx = 0 kx + 2ky + rx + 2ry = 0 + -2ry + 2ry kx + 2ky + rx + 2ry = -2ry + 2ry Combine like terms: -2ry + 2ry = 0 kx + 2ky + rx + 2ry = 0 The solution to this equation could not be determined.
