Solution for ln(2n+6)=ln(-5n-1) equation:


Simplifying
ln(2n + 6) = ln(-5n + -1)

Reorder the terms:
ln(6 + 2n) = ln(-5n + -1)
(6 * ln + 2n * ln) = ln(-5n + -1)
(6ln + 2ln2) = ln(-5n + -1)

Reorder the terms:
6ln + 2ln2 = ln(-1 + -5n)
6ln + 2ln2 = (-1 * ln + -5n * ln)
6ln + 2ln2 = (-1ln + -5ln2)

Solving
6ln + 2ln2 = -1ln + -5ln2

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add 'ln' to each side of the equation.
6ln + ln + 2ln2 = -1ln + ln + -5ln2

Combine like terms: 6ln + ln = 7ln
7ln + 2ln2 = -1ln + ln + -5ln2

Combine like terms: -1ln + ln = 0
7ln + 2ln2 = 0 + -5ln2
7ln + 2ln2 = -5ln2

Add '5ln2' to each side of the equation.
7ln + 2ln2 + 5ln2 = -5ln2 + 5ln2

Combine like terms: 2ln2 + 5ln2 = 7ln2
7ln + 7ln2 = -5ln2 + 5ln2

Combine like terms: -5ln2 + 5ln2 = 0
7ln + 7ln2 = 0

Factor out the Greatest Common Factor (GCF), '7ln'.
7ln(1 + n) = 0

Ignore the factor 7.

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + n)' equal to zero and attempt to solve: Simplifying 1 + n = 0 Solving 1 + n = 0 Move all terms containing l to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + n = 0 + -1 Combine like terms: 1 + -1 = 0 0 + n = 0 + -1 n = 0 + -1 Combine like terms: 0 + -1 = -1 n = -1 Add '-1n' to each side of the equation. n + -1n = -1 + -1n Combine like terms: n + -1n = 0 0 = -1 + -1n Simplifying 0 = -1 + -1n The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
