Simplifying ln(x + 9) + -1ln(x + -9) = 0 Reorder the terms: ln(9 + x) + -1ln(x + -9) = 0 (9 * ln + x * ln) + -1ln(x + -9) = 0 (9ln + lnx) + -1ln(x + -9) = 0 Reorder the terms: 9ln + lnx + -1ln(-9 + x) = 0 9ln + lnx + (-9 * -1ln + x * -1ln) = 0 9ln + lnx + (9ln + -1lnx) = 0 Reorder the terms: 9ln + 9ln + lnx + -1lnx = 0 Combine like terms: 9ln + 9ln = 18ln 18ln + lnx + -1lnx = 0 Combine like terms: lnx + -1lnx = 0 18ln + 0 = 0 18ln = 0 Solving 18ln = 0 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Divide each side by '18'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
