Solution for ln(-4y+8)-ln(y+7)=ln(-12y+13) equation:


Simplifying
ln(-4y + 8) + -1ln(y + 7) = ln(-12y + 13)

Reorder the terms:
ln(8 + -4y) + -1ln(y + 7) = ln(-12y + 13)
(8 * ln + -4y * ln) + -1ln(y + 7) = ln(-12y + 13)
(8ln + -4lny) + -1ln(y + 7) = ln(-12y + 13)

Reorder the terms:
8ln + -4lny + -1ln(7 + y) = ln(-12y + 13)
8ln + -4lny + (7 * -1ln + y * -1ln) = ln(-12y + 13)
8ln + -4lny + (-7ln + -1lny) = ln(-12y + 13)

Reorder the terms:
8ln + -7ln + -4lny + -1lny = ln(-12y + 13)

Combine like terms: 8ln + -7ln = 1ln
1ln + -4lny + -1lny = ln(-12y + 13)

Combine like terms: -4lny + -1lny = -5lny
1ln + -5lny = ln(-12y + 13)

Reorder the terms:
1ln + -5lny = ln(13 + -12y)
1ln + -5lny = (13 * ln + -12y * ln)
1ln + -5lny = (13ln + -12lny)

Solving
1ln + -5lny = 13ln + -12lny

Solving for variable 'l'.

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

Add '-13ln' to each side of the equation.
1ln + -13ln + -5lny = 13ln + -13ln + -12lny

Combine like terms: 1ln + -13ln = -12ln
-12ln + -5lny = 13ln + -13ln + -12lny

Combine like terms: 13ln + -13ln = 0
-12ln + -5lny = 0 + -12lny
-12ln + -5lny = -12lny

Add '12lny' to each side of the equation.
-12ln + -5lny + 12lny = -12lny + 12lny

Combine like terms: -5lny + 12lny = 7lny
-12ln + 7lny = -12lny + 12lny

Combine like terms: -12lny + 12lny = 0
-12ln + 7lny = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-12 + 7y) = 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.
