Simplifying ln(x + 8) = ln(x + 9) Reorder the terms: ln(8 + x) = ln(x + 9) (8 * ln + x * ln) = ln(x + 9) (8ln + lnx) = ln(x + 9) Reorder the terms: 8ln + lnx = ln(9 + x) 8ln + lnx = (9 * ln + x * ln) 8ln + lnx = (9ln + lnx) Add '-1lnx' to each side of the equation. 8ln + lnx + -1lnx = 9ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 8ln + 0 = 9ln + lnx + -1lnx 8ln = 9ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 8ln = 9ln + 0 8ln = 9ln Solving 8ln = 9ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-9ln' to each side of the equation. 8ln + -9ln = 9ln + -9ln Combine like terms: 8ln + -9ln = -1ln -1ln = 9ln + -9ln Combine like terms: 9ln + -9ln = 0 -1ln = 0 Divide each side by '-1'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
