Solution for ln(-3y+6)-ln(y+2)=ln(-9y-12) equation:


Simplifying
ln(-3y + 6) + -1ln(y + 2) = ln(-9y + -12)

Reorder the terms:
ln(6 + -3y) + -1ln(y + 2) = ln(-9y + -12)
(6 * ln + -3y * ln) + -1ln(y + 2) = ln(-9y + -12)
(6ln + -3lny) + -1ln(y + 2) = ln(-9y + -12)

Reorder the terms:
6ln + -3lny + -1ln(2 + y) = ln(-9y + -12)
6ln + -3lny + (2 * -1ln + y * -1ln) = ln(-9y + -12)
6ln + -3lny + (-2ln + -1lny) = ln(-9y + -12)

Reorder the terms:
6ln + -2ln + -3lny + -1lny = ln(-9y + -12)

Combine like terms: 6ln + -2ln = 4ln
4ln + -3lny + -1lny = ln(-9y + -12)

Combine like terms: -3lny + -1lny = -4lny
4ln + -4lny = ln(-9y + -12)

Reorder the terms:
4ln + -4lny = ln(-12 + -9y)
4ln + -4lny = (-12 * ln + -9y * ln)
4ln + -4lny = (-12ln + -9lny)

Solving
4ln + -4lny = -12ln + -9lny

Solving for variable 'l'.

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

Add '12ln' to each side of the equation.
4ln + 12ln + -4lny = -12ln + 12ln + -9lny

Combine like terms: 4ln + 12ln = 16ln
16ln + -4lny = -12ln + 12ln + -9lny

Combine like terms: -12ln + 12ln = 0
16ln + -4lny = 0 + -9lny
16ln + -4lny = -9lny

Add '9lny' to each side of the equation.
16ln + -4lny + 9lny = -9lny + 9lny

Combine like terms: -4lny + 9lny = 5lny
16ln + 5lny = -9lny + 9lny

Combine like terms: -9lny + 9lny = 0
16ln + 5lny = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(16 + 5y) = 0

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 '(16 + 5y)' equal to zero and attempt to solve: Simplifying 16 + 5y = 0 Solving 16 + 5y = 0 Move all terms containing l to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + 5y = 0 + -16 Combine like terms: 16 + -16 = 0 0 + 5y = 0 + -16 5y = 0 + -16 Combine like terms: 0 + -16 = -16 5y = -16 Add '-5y' to each side of the equation. 5y + -5y = -16 + -5y Combine like terms: 5y + -5y = 0 0 = -16 + -5y Simplifying 0 = -16 + -5y 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.
