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.
2ln + lnx + -5nL + -18ln + nxL = 18ln + -18ln

Reorder the terms:
2ln + -18ln + lnx + -5nL + nxL = 18ln + -18ln

Combine like terms: 2ln + -18ln = -16ln
-16ln + lnx + -5nL + nxL = 18ln + -18ln

Combine like terms: 18ln + -18ln = 0
-16ln + lnx + -5nL + nxL = 0

Add '5nL' to each side of the equation.
-16ln + lnx + -5nL + 5nL + nxL = 0 + 5nL

-16ln + lnx + 0 + nxL = 0 + 5nL
-16ln + lnx + nxL = 0 + 5nL
Remove the zero:
-16ln + lnx + nxL = 5nL

Add '-1nxL' to each side of the equation.
-16ln + lnx + nxL + -1nxL = 5nL + -1nxL

Combine like terms: nxL + -1nxL = 0
-16ln + lnx + 0 = 5nL + -1nxL
-16ln + lnx = 5nL + -1nxL

Reorder the terms:
-16ln + lnx + -5nL + nxL = 5nL + -5nL + -1nxL + nxL

Combine like terms: 5nL + -5nL = 0
-16ln + lnx + -5nL + nxL = 0 + -1nxL + nxL
-16ln + lnx + -5nL + nxL = -1nxL + nxL

Combine like terms: -1nxL + nxL = 0
-16ln + lnx + -5nL + nxL = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(-16l + lx + -5L + xL) = 0

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing l to the left, all other terms to the right. Add '-1n' to each side of the equation. n + -1n = 0 + -1n Remove the zero: 0 = -1n Simplifying 0 = -1n 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 '(-16l + lx + -5L + xL)' equal to zero and attempt to solve: Simplifying -16l + lx + -5L + xL = 0 Reorder the terms: -5L + -16l + lx + xL = 0 Solving -5L + -16l + lx + xL = 0 Move all terms containing l to the left, all other terms to the right. Add '5L' to each side of the equation. -5L + -16l + lx + 5L + xL = 0 + 5L Reorder the terms: -5L + 5L + -16l + lx + xL = 0 + 5L Combine like terms: -5L + 5L = 0 0 + -16l + lx + xL = 0 + 5L -16l + lx + xL = 0 + 5L Remove the zero: -16l + lx + xL = 5L Add '-1xL' to each side of the equation. -16l + lx + xL + -1xL = 5L + -1xL Combine like terms: xL + -1xL = 0 -16l + lx + 0 = 5L + -1xL -16l + lx = 5L + -1xL The solution to this equation could not be determined.
