Solution for ln(-6y+7)-ln(y+4)=ln(-11y-6) equation:


Simplifying
ln(-6y + 7) + -1ln(y + 4) = ln(-11y + -6)

Reorder the terms:
ln(7 + -6y) + -1ln(y + 4) = ln(-11y + -6)
(7 * ln + -6y * ln) + -1ln(y + 4) = ln(-11y + -6)
(7ln + -6lny) + -1ln(y + 4) = ln(-11y + -6)

Reorder the terms:
7ln + -6lny + -1ln(4 + y) = ln(-11y + -6)
7ln + -6lny + (4 * -1ln + y * -1ln) = ln(-11y + -6)
7ln + -6lny + (-4ln + -1lny) = ln(-11y + -6)

Reorder the terms:
7ln + -4ln + -6lny + -1lny = ln(-11y + -6)

Combine like terms: 7ln + -4ln = 3ln
3ln + -6lny + -1lny = ln(-11y + -6)

Combine like terms: -6lny + -1lny = -7lny
3ln + -7lny = ln(-11y + -6)

Reorder the terms:
3ln + -7lny = ln(-6 + -11y)
3ln + -7lny = (-6 * ln + -11y * ln)
3ln + -7lny = (-6ln + -11lny)

Solving
3ln + -7lny = -6ln + -11lny

Solving for variable 'l'.

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

Add '6ln' to each side of the equation.
3ln + 6ln + -7lny = -6ln + 6ln + -11lny

Combine like terms: 3ln + 6ln = 9ln
9ln + -7lny = -6ln + 6ln + -11lny

Combine like terms: -6ln + 6ln = 0
9ln + -7lny = 0 + -11lny
9ln + -7lny = -11lny

Add '11lny' to each side of the equation.
9ln + -7lny + 11lny = -11lny + 11lny

Combine like terms: -7lny + 11lny = 4lny
9ln + 4lny = -11lny + 11lny

Combine like terms: -11lny + 11lny = 0
9ln + 4lny = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(9 + 4y) = 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.
