5ln + 8lnx = (-18 * ln + 6x * ln)
5ln + 8lnx = (-18ln + 6lnx)

Solving
5ln + 8lnx = -18ln + 6lnx

Solving for variable 'l'.

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

Add '18ln' to each side of the equation.
5ln + 18ln + 8lnx = -18ln + 18ln + 6lnx

Combine like terms: 5ln + 18ln = 23ln
23ln + 8lnx = -18ln + 18ln + 6lnx

Combine like terms: -18ln + 18ln = 0
23ln + 8lnx = 0 + 6lnx
23ln + 8lnx = 6lnx

Add '-6lnx' to each side of the equation.
23ln + 8lnx + -6lnx = 6lnx + -6lnx

Combine like terms: 8lnx + -6lnx = 2lnx
23ln + 2lnx = 6lnx + -6lnx

Combine like terms: 6lnx + -6lnx = 0
23ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(23 + 2x) = 0

Subproblem 1
