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

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

Solving for variable 'l'.

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

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

Combine like terms: 18ln + -8ln = 10ln
10ln + 6lnx = 8ln + -8ln + 5lnx

Combine like terms: 8ln + -8ln = 0
10ln + 6lnx = 0 + 5lnx
10ln + 6lnx = 5lnx

Add '-5lnx' to each side of the equation.
10ln + 6lnx + -5lnx = 5lnx + -5lnx

Combine like terms: 6lnx + -5lnx = 1lnx
10ln + 1lnx = 5lnx + -5lnx

Combine like terms: 5lnx + -5lnx = 0
10ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(10 + x) = 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 '(10 + x)' equal to zero and attempt to solve: Simplifying 10 + x = 0 Solving 10 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 0 + -10 Combine like terms: 10 + -10 = 0 0 + x = 0 + -10 x = 0 + -10 Combine like terms: 0 + -10 = -10 x = -10 Add '-1x' to each side of the equation. x + -1x = -10 + -1x Combine like terms: x + -1x = 0 0 = -10 + -1x Simplifying 0 = -10 + -1x 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.
