Simplifying ln(y + 2) = ln(y + -7) + ln(4) Reorder the terms: ln(2 + y) = ln(y + -7) + ln(4) (2 * ln + y * ln) = ln(y + -7) + ln(4) (2ln + lny) = ln(y + -7) + ln(4) Reorder the terms: 2ln + lny = ln(-7 + y) + ln(4) 2ln + lny = (-7 * ln + y * ln) + ln(4) 2ln + lny = (-7ln + lny) + ln(4) Reorder the terms for easier multiplication: 2ln + lny = -7ln + lny + 4ln Reorder the terms: 2ln + lny = -7ln + 4ln + lny Combine like terms: -7ln + 4ln = -3ln 2ln + lny = -3ln + lny Add '-1lny' to each side of the equation. 2ln + lny + -1lny = -3ln + lny + -1lny Combine like terms: lny + -1lny = 0 2ln + 0 = -3ln + lny + -1lny 2ln = -3ln + lny + -1lny Combine like terms: lny + -1lny = 0 2ln = -3ln + 0 2ln = -3ln Solving 2ln = -3ln Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '3ln' to each side of the equation. 2ln + 3ln = -3ln + 3ln Combine like terms: 2ln + 3ln = 5ln 5ln = -3ln + 3ln Combine like terms: -3ln + 3ln = 0 5ln = 0 Divide each side by '5'. ln = 0 Simplifying ln = 0 The solution to this equation could not be determined.
