Reorder the terms for easier multiplication:
15ln * x + -2ln(1 + x) = ln(3)

Multiply ln * x
15lnx + -2ln(1 + x) = ln(3)
15lnx + (1 * -2ln + x * -2ln) = ln(3)
15lnx + (-2ln + -2lnx) = ln(3)

Reorder the terms:
-2ln + 15lnx + -2lnx = ln(3)

Combine like terms: 15lnx + -2lnx = 13lnx
-2ln + 13lnx = ln(3)

Reorder the terms for easier multiplication:
-2ln + 13lnx = 3ln

Solving
-2ln + 13lnx = 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 + 13lnx = 3ln + -3ln

Combine like terms: -2ln + -3ln = -5ln
-5ln + 13lnx = 3ln + -3ln

Combine like terms: 3ln + -3ln = 0
-5ln + 13lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-5 + 13x) = 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 '(-5 + 13x)' equal to zero and attempt to solve: Simplifying -5 + 13x = 0 Solving -5 + 13x = 0 Move all terms containing l to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + 13x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 13x = 0 + 5 13x = 0 + 5 Combine like terms: 0 + 5 = 5 13x = 5 Add '-13x' to each side of the equation. 13x + -13x = 5 + -13x Combine like terms: 13x + -13x = 0 0 = 5 + -13x Simplifying 0 = 5 + -13x 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.
