Simplifying ln(x + 2) = ln(x + -7) Reorder the terms: ln(2 + x) = ln(x + -7) (2 * ln + x * ln) = ln(x + -7) (2ln + lnx) = ln(x + -7) Reorder the terms: 2ln + lnx = ln(-7 + x) 2ln + lnx = (-7 * ln + x * ln) 2ln + lnx = (-7ln + lnx) Add '-1lnx' to each side of the equation. 2ln + lnx + -1lnx = -7ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 2ln + 0 = -7ln + lnx + -1lnx 2ln = -7ln + lnx + -1lnx Combine like terms: lnx + -1lnx = 0 2ln = -7ln + 0 2ln = -7ln Solving 2ln = -7ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '7ln' to each side of the equation. 2ln + 7ln = -7ln + 7ln Combine like terms: 2ln + 7ln = 9ln 9ln = -7ln + 7ln Combine like terms: -7ln + 7ln = 0 9ln = 0 Divide each side by '9'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
