Solving for variable 'l'.

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

Add '-9ln' to each side of the equation.
-5lnx + -9ln + 3lnx2 = 9ln + -9ln + lnx

Reorder the terms:
-9ln + -5lnx + 3lnx2 = 9ln + -9ln + lnx

Combine like terms: 9ln + -9ln = 0
-9ln + -5lnx + 3lnx2 = 0 + lnx
-9ln + -5lnx + 3lnx2 = lnx

Add '-1lnx' to each side of the equation.
-9ln + -5lnx + -1lnx + 3lnx2 = lnx + -1lnx

Combine like terms: -5lnx + -1lnx = -6lnx
-9ln + -6lnx + 3lnx2 = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-9ln + -6lnx + 3lnx2 = 0

Factor out the Greatest Common Factor (GCF), '3ln'.
3ln(-3 + -2x + x2) = 0

Factor a trinomial.
3ln((-1 + -1x)(3 + -1x)) = 0

Ignore the factor 3.

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 + -1x)' equal to zero and attempt to solve: Simplifying -1 + -1x = 0 Solving -1 + -1x = 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 + -1x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1x = 0 + 1 -1x = 0 + 1 Combine like terms: 0 + 1 = 1 -1x = 1 Add 'x' to each side of the equation. -1x + x = 1 + x Combine like terms: -1x + x = 0 0 = 1 + x Simplifying 0 = 1 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 3
